Central Chambers Law
Possession of an Offensive Weapon

An allegation of possessing an offensive weapon in a public place is a serious criminal offence. The law is designed to be deliberately broad, covering a wide range of items, and the police and courts treat these allegations with extreme gravity. A conviction can result in a prison sentence and a criminal record, which can have a lasting negative impact on your life, employment, and future. If you are under investigation or have been charged with this offence, securing immediate, expert legal advice is critical to protecting your rights and your good name.
At Central Chambers Law, our senior legal consultants are experts in defending individuals against all types of weapons-related allegations. We have a detailed and technical understanding of the law and the specific defences available. Our function is to provide clear, authoritative guidance and to meticulously scrutinise the prosecution's case to build a powerful and strategic defence on your behalf.
What is an Offensive Weapon? The Legal Definition
The primary law covering this offence is Section 1 of the Prevention of Crime Act 1953. This makes it an offence for a person to have an offensive weapon with them in a public place, without lawful authority or reasonable excuse.
The Act defines an "offensive weapon" in three distinct categories:
- Made: Any article made for causing injury to a person. This includes items like flick knives, knuckle dusters, and batons.
- Adapted: Any article adapted for use for causing injury. This could be a snooker ball in a sock or a bottle that has been deliberately broken to create a sharp edge.
- Intended: Any article which the person has with them with the intention of using it to cause injury. This is the broadest category and can include almost any everyday object, such as a hammer, a screwdriver, or a baseball bat, if the prosecution can prove you intended to use it as a weapon.
Breaking Down the Offence
For the prosecution to secure a conviction, they must prove two key elements beyond a reasonable doubt:
- You had an offensive weapon with you.
- This was in a public place.
If the item is not "made" or "adapted," the prosecution must also prove that you intended to use it to cause injury. Once the prosecution has established these points, the burden shifts to you to prove that you had "lawful authority or reasonable excuse."
"Public Place"
This is defined broadly as any place to which the public has access, whether by payment or not. It includes streets, parks, public transport, and entertainment venues. A car is also considered a public place if it is situated in one.
"Lawful Authority or Reasonable Excuse"
This is the central battleground in most offensive weapon cases. It is up to the accused to provide a credible explanation for possessing the item.
- Lawful Authority: This is a narrow defence, typically applying only to those who are required to carry the item as part of their official duty, such as a police officer with a baton.
- Reasonable Excuse: This is a broader defence based on the specific facts of the case. A common example is carrying an item for use at work, such as a carpenter with a hammer in their toolbag. The excuse must be genuine and credible.
The Penalties for a Conviction
Possession of an offensive weapon is an "either-way" offence, meaning it can be heard in either the Magistrates' Court or the Crown Court. The penalties are severe:
- Prison Sentence: The maximum sentence is four years' imprisonment. Even for a first offence, a custodial sentence is a very real possibility, especially if the weapon is in the "made" category.
- Criminal Record: A conviction for a weapons offence is extremely serious and will result in a criminal record. This can create significant barriers to employment, professional registrations, and international travel.
- Forfeiture: The weapon will be confiscated and destroyed by the court.
Building a Defence to the Allegation
An allegation is not a conviction. Many cases turn on the specific facts and intentions of the accused, and a specialist solicitor can identify and build a powerful defence.
Potential defences include:
- Reasonable Excuse: Proving that you had a legitimate and credible reason for possessing the item in a public place, such as for your work, for a hobby, or for another innocent purpose.
- Lack of Intention: If the item is not made or adapted for causing injury, the primary defence is to challenge the prosecution’s claim that you intended to use it as a weapon.
- Not a Public Place: Challenging the prosecution's assertion that the location where you were found with the item was legally a "public place."
- Lack of Knowledge: Arguing that you were not aware that you had the item with you. For example, if it was in a bag you had borrowed or had been forgotten from a previous legitimate use.
