London

The London-born sprinter once had a glittering career in front of him, building a reputation as one of the fastest Europeans in athletics history.

But in 2003 he came a cropper when he tested positive for a banned steroid, and was slapped with a two-year athletics ban and a lifetime one for the Olympics - as well as being stripped of his medals.

He’s now trying to rebuild his life and career.

Dwain has been competing at the European Championships in Turin, where he bagged his first big medal since the ban.

He was crowned 60m European Indoors champion after crushing the 60m field in a time of 6.46 seconds.

Dwain speaks candidly to Kurt Barling about his regrets, his suicidal thoughts, his hopes of competing for Britain in 2012, and his ongoing feud with Seb Coe.
