A 33-YEAR-OLD man has been arrested after a woman was sexually assaulted by a 'taxi driver'.

Police say the victim, aged in her 20s, fell asleep in the back of a taxi while travelling from Oxford to Abingdon and awoke to find the driver 'undoing her trousers'.

She told police she was then sexually assaulted.

The suspect has since been released under investigation.

The woman got into the car in Oxford's Park End Street at around 1.30am on Sunday, October 14.

She escaped from the vehicle in West St Helen Street, Abingdon.

Officers have not yet said if they believe the car to be a genuine licensed taxi and are still appealing for witnesses.

Secretary of the City of Oxford Licensed Taxicab Association (COLTA), Sajad Khan said: “It’s a very unfortunate thing that’s happened and I really hope that the police get to the bottom of it and find the culprit."
