How do you become embroiled in a gang? And is there an escape from a life of violence and crime?
BBC Newsnight tells the story of a former London gang member, through an animation voiced by an actor.
He describes the drug dealing and knife crime that shaped his time in the gang, and what prompted him to leave that way of life behind.
