A youth questioned over the alleged rape of a woman who said she was dragged into a park and attacked has been released on bail.

Police are continuing to appeal for witnesses to the incident, which is said to have occured as the 19-year-old walked along Between Towns Road, in Cowley, at about 8.30pm on Saturday.

Officers believe two young Asian men and a man in his 60s near a kebab van may have seen the suspected rapist, who police believe was riding a silver bicycle.

So far, none of them have come forward.

Police said after the alleged attack the woman was marched at knifepoint to a nearby cash machine where he tried to make her withdraw money.

She managed to raise the alarm by alerting door staff at the William Morris Wetherspoon's pub.

The alleged attacker was described as Asian, about 6ft tall, wearing a dark jumper with multi-coloured horizontal stripes and a baseball cap and said to be 16 or 17 years old. He is alleged to have stolen the woman's Nokia 5300 mobile phone.
