A 20-year-old man had to fight off and flee a sex attacker at Redbridge park-and-ride.

Police said today the victim got into a car, which he mistakenly believed was a taxi, in Botley Road at 2.30am on Sunday and asked to be taken home.

However, he was taken to the park-and-ride site in South Oxford where he was sexually assaulted.

He managed to fight off the man - who is described as Asian, aged in his late 20s to early 30s and driving a two-door blue car - and then hid in some bushes.

Det Con Mel Steel, of Oxford CID, said: "After the assault took place the victim flagged down a silver Citroen. A woman and her son, who were in the car, advised him to contact police before driving off.

"He then pulled over a passing taxi and asked the driver to take him to his home address. I appeal to both these people, who helped out the victim, to contact police as they may be able to assist our enquiries."

Anyone with information can call Det Con Steel at Oxford police on 08458 505505 or Crimestoppers anonymously on 0800 555111.
