British rapper Professor Green is reportedly facing a police investigation over an alleged hit and run in London.

The I Need You Tonight hitmaker is accused of reversing his loaned Mercedes into an elderly man's parked Vauxhall Vectra and causing $1,280 (£800) worth of damage.

Albert Stanford, 67, claims he saw the white Mercedes collide with his car but was unable to obtain the driver's insurance details.

He tells Britain's The Sun, "It made a loud smash. But by the time I got my dressing gown on and went down, they had driven off."

Neighbours apparently told Stanford the car belonged to Professor Green, whose grandmother lives nearby, but the hip-hop star insists his luxury vehicle was undamaged.

He says, "The matter is being looked into," while a spokesperson for the Metropolitan Police adds, "This is being treated as a fail-to-stop collision."
