A teacher accused of indecently assaulting a 19-year-old woman has told a jury the woman made her story up.

Maths teacher John Howard, 49, of Hastings Hill, Churchill, near Chipping Norton, denies a single charge of indecent assault.

He told Oxford Crown Courton Wednesday that the young woman had lied in her statement to police and in her evidence to the jury.

Earlier, the complainant had told the court Howard had gone into a bedroom and woken her by stroking her body.

She said he later chatted to her about her present boyfriend and ex-boyfriends before moving towards her, touching her breast and kissing her in a way that made her feel uncomfortable.

He told police during interview he was not attracted to the woman in any sexual way.

"I'm saying categorically I didn't touch her in any sexual way or form at all," he said.

Paul Reid, prosecuting, asked him: "You had told police that she lied in her statement?"

Howard replied: "Yes, definitely."

Mr Reid added: "You have told the jury that she lied in her evidence?"

Howard said: "Yes."

Howard told the court he was "99.9 per cent sure" he had gone into the bedroom where he is alleged to have stroked the young woman's body on the night in question, but did not remember seeing her there.

The trial continues.
