Whilst volunteering with Spark2Life, rapper Cerose was set a challenge by CEO Dez Brown to put together a rap based on gun and knife crime in inner city areas and the #LondonNeedsYouAlive message.

"As a pioneer in UK hip hop and a reformed criminal, I was happy to use my talents to send a positive message to youngsters in words they can understand."

You can listen to Cerose's rap below.
