A bus driver faces jail after he sexually assaulted a judge's daughter on the Oxford Tube service.

Mark Arthurs, 37, of Saxton Road, Abingdon, stopped the bus and attacked her on the top deck as she travelled from Oxford to London.

He denied two charges of indecent assault and one of false imprisonment, but was convicted on one charge of indecent assault by a jury in London.

Blackfriars Crown Court heard that the woman, in her early 20s, was sitting at the front of the double-decker coach and chatting to father-of-two Arthurs.

The court was told she began to feel uncomfortable when he "began to turn the conversation to sexual innuendos".

Steven Perian, prosecuting, said that Arthurs stopped the bus at Shepherds Bush, turned off the lights, dragged her to the back of the coach and indecently assaulted her.

Arthurs, whose tachograph indicated he had stopped for seven minutes, then drove to the next stop, Notting Hill Gate.

He pulled up again, grabbed the woman, asked her to come upstairs and indecently assaulted her again.

The woman called the police after managing to get off the bus at Notting Hill Gate.

Giving evidence, she said she stayed on the bus after the first incident on December 13 last year because she was frightened.

When Arthurs was interviewed, he admitted kissing her twice at Shepherds Bush, but denied anything further happened. He told police the woman had pushed herself against him.

In court, he said his thoughts at the time were: "I'm married with two children. I'm not going to let this happen".

Judge Brian Pryor Pryor adjourned sentencing but warned Arthurs: "All sentencing options remain open."
