Mothers back 'Iron Angel' anti-knife campaign

The mothers of three men who were stabbed to death have lent their support to an anti-knife campaign.
The Save a Life Surrender Your Knife project aims to collect weapons handed in by current and former gang members and turn them into a sculpture of an angel.
Alison Cope, whose son rapper Joshua Ribera was murdered in Selly Oak, West Midlands in September, met Lisa McNeill and Lisa Minott, whose sons were also fatally stabbed.
The campaign is expected to see knives used in a sculpture, with each one representing a feather in the wings of a 20-ft-high angel.
Clive Knowles, managing director of the British Ironworks Centre, which will design and make the sculpture, said more than 30 knives had so far been handed in.
