Mr Downes, from Harlesden, was arrested on Friday and was later charged with two counts of rape. He was due to appear before Brent magistrates' court today. The Police Complaints Authority will supervise the investigation into his death; a post-mortem examination was due to be held yesterday.
An investigation was launched yesterday after a man accused of rape was found hanging in a police cell. Marlon Downes, 20, was found at 3am at Harlesden police station, north-west London. Police officers tried to resuscitate him and he was taken to the Central Middlesex Hospital, also in north-west London, where he was pronounced dead at 4am.
