This hard-hitting photo shows just some of the knives handed into police as part of a five-day amnesty in Bradford.

West Yorkshire Police's knife bin at Trafalgar House Police Station will remain in place until 8pm on Friday. 

It comes after new legislation means people are committing an offence if they carry 20 different types of weapons - including knuckledusters, zombie knives and shurikens.
