A weapons amnesty has been launched by West Yorkshire Police.
And stabbing victim Vincent Uzomah is backing the campaign, giving people the chance to hand over guns and other weapons.
The weapons surrender, until January 30, involves police urging members of the public to hand in any weapons they hold including knives and offensive weapons
Mr Uzomah, aged 51, of Leeds, is supporting the campaign and appealing for people to hand in any weapons so they are not used to cause injury to others.
He was working as a teacher at Dixons Kings Academy in Bradford in June last year when he was stabbed by a teenage boy*
He said:“Weapons are not toys, so please do not carry one. I nearly lost my life in the hand of a knife-carrying student in school, and my family was devastated. Our society is safer when you don’t carry one, hand in any weapon in your possession today please”.
During the campaign those surrendering firearms, ammunition, knives and other offensive weapons will not face prosecution.
Asst Chief Constable Angela Williams said: “While we continue to maintain a low number of recorded crimes involving guns, knives and other weapons, we take it extremely seriously. We had a good response to a similar campaign in November 2014 when more than 150 knives and other weapons were handed in.”
Special collection bins will be in police stations including Dewsbury and Halifax
