Professor Green was arrested on suspicion of driving under the influence of alcohol (DUI) last weekend after police found his car and another van had been involved in a collision.
The 29-year-old rapper phoned the police in the early hours of Sunday morning (03.11.13) after he was mugged outside his house for his Rolex watch, but after officers turned up at the scene they found his Mercedes and a van had been involved in a collision, and later pulled him into custody on suspicion of drink driving.
A spokesperson for Scotland Yard told the daily Mirror newspaper: "The suspected driver of the car, a 29-year-old man, was arrested on suspicion of drink driving and taken into custody at a South London police station.
"There were no reports of any injured parties. Inquiries into the robbery and the collision are ongoing."
It is believed the 'Read All About It' hitmaker had been out clubbing in London on the night of his arrest.
He also shared a photograph on Instagram earlier on in the day, which saw him on board an aeroplane with empty bottles of vodka.
It is not thought his wife Millie Mackintosh was at the south London home when the star phoned the police at 2:40am.
Professor Green has been bailed until the end of the month.
