The life and death of a stunt biker: Father's helmet regret
The father of a 21-year-old stunt biker killed in a quad bike crash in Coventry has broken down in tears as he revealed his son was not wearing a helmet.
Tyrone Evans performed high-risk stunts on his bike and many videos of these went viral on social media.

He is urging other stunt bikers to wear a helmet.
