Knife crime: 'I take my eye out and it hits home'
Mark Bracewell is a former gang member who lost an eye when he was stabbed.
Since leaving his past behind him, the 44-year-old uses his experiences - and his injury - to warn youngsters about knife crime.
He delivers workshops in schools with the group Blinded Faith, and uses his prosthetic eye as a shock tactic.
"I take my eye out out... and it hits home," he says.
