Rapper Professor Green phoned police after he was mugged outside his house – but HE was the one who got arrested.

The hip-hop star, 29, was hauled into custody on suspicion of drink driving.

Green called police when his Rolex watch was snatched in the early hours.

Officers who arrived on the scene carted him off after they found his Mercedes and a van had been involved in a crash.

The star, real name Stephen Manderson, is thought to have been clubbing on the night of the arrest.

Hours before, he had been on a flight where he posted photos of vodka bottles on picture-sharing website Instagram.

His wife, Made in Chelsea star Millie Mackintosh , 23, is not thought to have been at the South London home when he called police at 2.40am on Sunday.

Scotland Yard said: “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.”

The rapper – who had a No1 hit in 2011 with Read All About It, which featured vocalist Emeli Sandé – has been bailed to return to a police station at the end of the month.

Yesterday a spokesman for Green declined to comment on the arrest.
