POLICE are investigating claims that a woman from Purley was sexually assaulted by a man claiming to be a taxi driver on her way back from the weekend's Epsom Derby.
The woman, in her 20s, was coming back from a party in Tadworth, Surrey, on Saturday when a man offered her a lift in his car.
When she refused, she said the man pushed her to the ground and assaulted her in the street.
She managed to escape the man and fled to Tattenham Corner station, where a man helped her onto a train home at about 10pm.
Surrey Police are now carrying out a house-to-house investigation to try and locate the exact spot the woman was attacked.
The suspect has been described as black, with short hair, muscular and with a south London accent. He was wearing a white T-shirt with a collar and dark trousers.
Detective Sergeant Mark Parry appealed for witnesses and anyone with information to come forward.
The victim also lost two gold bangles during the attack.
Contact Detective Sergeant Parry by calling Surrey Police on 101.
