London Metropolitan police commissions video to tackle knife crime

Britain's biggest police force has commissioned a shocking video to warn teenagers of the dangers of carrying a knife.

The short film by the Metropolitan police will be shown on MTV and other music TV channels and will focus on the impact a stabbing has on the families of the characters.

The Mirror has called for shock tactics as part of our Stop Lives, Save Knives drive.

One idea for the video includes two teenagers, one who carries a knife and one who doesn't, in a confrontation which leaves one dead.
