Knife crime is crime involving a knife. It's a crime to threaten someone with a knife or carry a knife as a weapon in a robbery or burglary. Police can search you if they think you're carrying a knife. Some knives are offensive weapons and are banned in public places.
What counts as knife crime
Knife crime includes:
- carrying a knife or trying to buy one if you’re under 18
- threatening someone with a knife
- carrying a knife that's banned
- a murder where the victim was stabbed with a knife
- a robbery or burglary where a thief carried a knife as a weapon
An offensive weapon is:
- an article designed to cause injury to another person
- an article carried with the intention of causing injury to another person
Penalties for knife crime
The law on knives says:
- it is illegal for anyone, including a shop, to sell a knife of any kind (including cutlery and kitchen knives) to anyone under the age of 18
- if you’re under 18, it’s illegal to buy most types of knives
- anyone over 10 can be charged and taken to court if they’re caught with an illegal knife – even if it’s the first time they’ve been stopped by the police
- if you're caught carrying a knife, you could receive a community sentence, a fine or imprisoned
- you could be searched at any time if a police officer thinks you may be carrying a knife
- even if you’re carrying a knife that you’re legally allowed to (like a penknife with a blade that’s shorter than three inches), it becomes illegal if you use it as a weapon to threaten or harm anyone
The maximum sentence for carrying a knife illegally is four years in prison and an unlimited fine. If you injure someone or use a knife to commit a crime, the penalties could increase.
