A jury has heard evidence from a 13-year-old schoolgirl who claims she was sexually attacked as she took a short cut home.

The teenager, who cannot be identified for legal reasons, described how her school tie was forced into her mouth as she was dragged from a footpath across derelict land and taken behind some trees in the Bierley area of Bradford last September.

The youngster claims her attacker then pinned her down on the ground but the ordeal suddenly ended when he stood up and walked away.

The teenager did not report the alleged attack when she got home, but after she told a school friend the next day the police were contacted.

She told them that her attacker was a man she knew called Anthony Greenwood and he was arrested a few days later.

Greenwood has pleaded not guilty to a charge of attempted rape and an alternative allegation of indecent assault.

Prosecutor Howard Crowson told Bradford Crown Court yesterday that when Greenwood was arrested he told officers: "You've got no forensic.''

During questioning Greenwood, 24, of no fixed address, denied being involved in the offence, but accepted he had been visiting his mother in the area that day.

The girl was questioned about her allegation in a specialist unit at Eccleshill police station and yesterday the jury was shown a video of her interview. In it she described how Greenwood grabbed her round the waist as she tried to walk past him and dragged her away pushing her tie into her mouth. "I thought he was going to try to have sex with me,'' she told the interviewing officer.

She said she thought when Greenwood stopped and walked off he might have heard a noise.

During cross-examination by his barrister Colin Harvey she rejected his suggestion that she had blamed Greenwood for a previous incident before changing her mind and saying it was someone else.

The girl accepted that she didn't like or trust Greenwood but denied making up allegation.

The trial continues.
