A senior Met Police officer who was found slumped over the wheel of his car has been arrested on suspicion of dealing Class A drugs.
Ch Insp Paul Cahill MBE was found in Wandsworth Road in Lambeth by passing policemen.
When officers searched the 43-year-old's vehicle they allegedly uncovered a stash of Class A drugs.
He was arrested on suspicion of possessing Class A drugs with intent to supply and being made unfit to drive through alcohol or drugs.
Ch Insp Cahill has been suspended from his duties as a member of Westminster borough command.
Mr Cahill hit the headlines after becoming the victim of a homophobic attack in 1996 and a year later he appeared on the front of the Gay Times in full police uniform.
He was awarded an MBE in 2004 for his work on promoting diversity in the police force.
