Knife Crime, Weapons and Staying Safe

A calm, plain-English United Kingdom guide for young people, parents, carers, teachers, youth workers and anyone who is worried. It explains why carrying a weapon increases danger, what the law says in England and Wales, Scotland and Northern Ireland, what to do if you are being pressured to carry or hide something, how to surrender a weapon safely, and where to find urgent or anonymous help.

Carrying a knife does not make you safer
Carrying a knife does not make you safer. It puts a weapon into every argument, every misunderstanding and every moment of panic. A decision made in seconds can end one life and destroy many others.
Spoken plainly, and without drama:
- A person can be injured or killed with the weapon they were carrying themselves.
- Another person can die, or be left with life-changing injuries.
- The person carrying it can lose their freedom, their education, their job and the plans they had for their life.
- Families, friends and witnesses can live with what happened for years afterwards.
- Carrying a weapon because of fear, bullying, threats or gang pressure does not mean it is too late to ask for help.
- Asking for help is not weakness. It is one of the few things that can stop what happens next, and it could save a life.
This page speaks directly to young people, and it is also written for parents, carers, teachers, youth workers, social workers and anyone else who is worried. It does not assume that any young person is a criminal.
Weapon present or someone in immediate danger — call 999
Call 999 now if:
- someone has a knife, firearm or other weapon and may use it
- a weapon is being used to threaten someone
- an attack is happening, or has just happened
- shots have been heard
- someone has been stabbed, shot or seriously injured
- someone is being forced into a vehicle or taken somewhere
- there is an immediate risk to life
What to do:
- Move away if you can do so safely.
- Do not confront the person, and do not try to grab or take the weapon.
- Call 999 and follow the call handler’s instructions exactly.
- If it is safe to speak, give the location, a description of the person, the direction they went, and what you saw about the weapon. Only give this if it is safe to do so.
- Do not put yourself in danger to film what is happening.
- Do not touch or move a weapon that has been left or abandoned — tell the police where it is.
- Serious bleeding or any serious injury needs emergency help immediately. If it is safe to help, firm pressure on serious external bleeding can be applied while you wait for the ambulance and follow the 999 call handler’s instructions.
If you cannot speak safely on a 999 call from a mobile, stay on the line and follow the automated instructions the operator gives you.
No immediate danger, but you are worried
- Call the police on 101.
- Report online through your local police force’s official reporting service.
- Contact Crimestoppers anonymously on 0800 555 111.
- Young people can use Fearless to pass on information anonymously.
- Speak to a trusted adult: a parent, carer, teacher, school safeguarding lead, college safeguarding team, youth worker or social worker.
- If the danger becomes immediate at any point, call 999.
Please understand: anonymous services such as Crimestoppers and Fearless pass information on, but they are not emergency services and cannot send anyone to help. They cannot provide an emergency response. Only 999 can do that.
Key points
- Carrying a weapon “for protection” can increase danger rather than remove it.
- A weapon can turn an argument, or a moment of panic, into a fatal incident.
- Being asked to carry, hide, transport or store a weapon for somebody else is serious, and is often part of how young people are exploited.
- An imitation firearm can still cause terror, trigger an armed police response and lead to serious criminal consequences.
- Someone who is being threatened or exploited needs protection and support, not judgement.
- It is never too late to step away and ask for help.
- Immediate danger always means 999.
What the law says
The law is different in England and Wales, in Scotland, and in Northern Ireland. Please read the section for the nation you are in. This is general information, not legal advice, and the law can change — always check the official source, and get legal advice about any individual situation.
England and Wales
Threatening someone. It is illegal to use any knife or weapon in a threatening way. Threatening another person with a blade or offensive weapon in a public place, in a school or in a private place is a separate and serious offence.
Carrying in public. Carrying most knives or bladed or pointed articles in a public place without a lawful reason (sometimes described in law as “good reason or lawful authority”) is an offence under section 139 of the Criminal Justice Act 1988. Carrying an offensive weapon in public without lawful authority or reasonable excuse is an offence under the Prevention of Crime Act 1953.
Examples of a lawful reason can include taking tools to work, carrying equipment for a trade, sport or religious observance, or transporting a knife you have just bought — properly wrapped and taken straight home. Whether a reason is lawful is decided by a court on the facts. It is never a lawful reason to carry something because you feel you might need it against another person.
The folding pocketknife exception. A folding pocketknife with a cutting edge of three inches (7.62cm) or less is treated differently under section 139. It must fold, and it must not lock open — a lock-knife is not covered by that exception. This is a narrow exception in the law and it is not permission to carry anything as a weapon. If an item is carried with the intention of using it to injure or threaten someone, that intention can make it an offensive weapon regardless of its size or type.
Ordinary objects. A lawful everyday object — a screwdriver, a tool, a bottle, a piece of sports equipment — can become an offensive weapon in law if it is carried with the intention of using it to injure someone.
Penalties. For an adult, the maximum penalty for illegally carrying a knife or an offensive weapon can be four years’ imprisonment, an unlimited fine, or both. More serious offences — threatening, causing injury, robbery, or possession with intent — can carry substantially heavier sentences. Repeat possession offences can bring minimum-sentence provisions, subject to the law and to what the court decides in the individual case.
Schools and colleges. Educational premises have additional legal protection: having a bladed article or offensive weapon on school premises is a specific offence, and further powers apply there.
Age. It is illegal to sell most knives to anyone under 18 anywhere in the UK, and some weapons are banned outright regardless of age.
Scotland
Scotland has its own criminal law, its own prosecution service (the Crown Office and Procurator Fiscal Service) and its own courts. Do not assume that penalties or terms used in England and Wales apply in Scotland.
Under the Criminal Law (Consolidation) (Scotland) Act 1995, it is an offence to have an offensive weapon in a public place without lawful authority or reasonable excuse, and it is a separate offence to have a knife or sharply pointed article in a public place without good reason or lawful authority. There are also specific offences relating to school premises.
Penalties in Scotland are set by Scottish legislation, and carrying a knife or offensive weapon can lead to a substantial prison sentence on conviction on indictment, as well as a fine. Police Scotland use stop-and-search powers where the law allows. Scotland’s approach also includes long-running public-health violence-prevention work.
Please check the current position with Police Scotland and the Scottish Government.
Northern Ireland
Northern Ireland has its own legislation, its own police service (the PSNI) and its own prosecution service (the Public Prosecution Service for Northern Ireland).
It is an offence in Northern Ireland to carry an offensive weapon in public without lawful authority or reasonable excuse, and to have a bladed or sharply pointed article in a public place without good reason or lawful authority, under the Criminal Justice (Northern Ireland) Order 1996. Threatening someone with a weapon and having a weapon on school premises are dealt with separately.
Age restrictions on the sale of knives apply in Northern Ireland, and penalties are set by Northern Ireland legislation. Please check current penalties and age rules with nidirect, the PSNI or the Department of Justice before relying on them.
Firearms and imitation firearms
Firearms law is complex, and offences vary considerably. What follows is only an outline. Every individual situation needs legal advice and should be checked against current official sources.
- Many firearms and types of ammunition require lawful authority, such as a certificate.
- Some weapons are prohibited outright.
- Possessing, carrying, supplying, hiding or using a firearm can lead to extremely serious charges.
- Firearms offences can carry long prison sentences. Some offences — for example possessing a firearm with intent to endanger life — can carry a maximum of life imprisonment. Different offences carry very different maximum sentences, and some carry minimum terms.
- An imitation firearm can still cause real fear, can trigger an armed police response, and can be part of very serious offences such as robbery or threatening someone.
- Being asked to store or “mind” a firearm or imitation for another person does not make the situation harmless, and does not remove responsibility.
Do not assume one universal sentence applies to all firearms offences — it does not. Check the CPS guidance and the legislation, and get legal advice.
If someone asks you to carry or hide a weapon
You may be told things like:
- “Hold this for me.”
- “Keep it at your house.”
- “Put it in your bag.”
- “Take it to somebody.”
- “You won’t get searched.”
- “Nothing will happen because you’re young.”
These are not favours between friends. They are often part of criminal exploitation — the risk is moved onto you while somebody else keeps the benefit.
What to do:
- Do not agree to carry, hold or move it.
- Move away when it is safe to do so.
- Do not confront the person on your own.
- Tell a trusted adult or a safeguarding professional what has happened.
- Call 999 if there is immediate danger.
- Use 101, Crimestoppers or Fearless when the danger is not immediate.
- Tell the police if you have been threatened, forced, blackmailed or frightened into it.
Nobody can promise that reporting automatically prevents arrest or prosecution. What is true is that coercion and exploitation are important information: they must be told to the police, to a solicitor and to safeguarding professionals, because they can affect decisions about charge, prosecution and support. Say it early, and say it clearly.
It is not too late to choose a different direction
Being frightened does not make you weak. Being pressured does not mean you have no choices. If somebody is making you carry, hide or use a weapon, tell a trusted adult or professional exactly what is happening.
One honest conversation could stop an injury, a death or a prison sentence. Asking for help may be the strongest decision you ever make.
Practical checklist
- Is anybody in immediate danger?
- Call 999 if a weapon is present or may be used.
- Move to safety if you can.
- Do not confront anyone, and do not attempt to disarm anyone.
- Do not film an unfolding emergency.
- Write down safe, factual information afterwards — times, descriptions, what was said.
- Tell a trusted adult.
- Contact the school or college safeguarding lead.
- Use 101 for non-emergency police concerns.
- Use Crimestoppers or Fearless for anonymous reporting.
- Explain any threats, coercion or exploitation to police, a solicitor and safeguarding staff.
- Do not agree to hold a weapon for someone else.
- Contact the police before attempting to surrender a weapon.
- Do not carry a weapon around looking for a surrender bin.
- Ask for legal advice after an arrest.
- Seek mental-health and bereavement support when it is needed.
