A 17-YEAR-OLD boy from the Cotswolds has gone on trial at Gloucester Crown Court accused of sexually abusing his sister over four years – including raping her three times.
The youth, who cannot be named for legal reasons, started going into her bedroom when she was 11 and looking at her body and then went on to touch her, the jury was told.
The abuse continued and he raped her three times, the court heard.
At one stage he threatened his sister with his knife if she didn't comply with his wishes.
She spoke out about the ordeal in December 2006, the jury heard.
The youth denies nine counts of sexual offences against the girl.
His trial began on Thursday at Gloucester Crown Court.
Crown Prosecutor Lynn Matthews said the girl involved – now 16 – had given a note to her father in early summer 2004 which said, her brother touched her.
When she was asked about it, she said he had touched her a couple of times but her brother denied any involvement with her at all, said Mrs Matthews.
On December 14, 2006, she confided in the assistant headteacher at school he had visited her bedroom since she was 12 and had touched her a couple of times a week.
After the note to her father the abuse stopped for a while but then resumed and continued until July 2006, the trial heard.
The assistant headteacher contacted the girl's mother and social services also became involved.
When challenged, the boy again denied the allegation.
The girl went to stay away from the family for a time and when she returned just before Christmas 2006, a lock was put on her door.
But on September 11 last year, the jury was told he knocked on her door and then caressed her breast before stooping to kiss her, but she turned away and he left the room.
The next day, she made a complaint and the police became involved, the jury heard.
The boy pleaded not guilty to indecently assaulting the girl between December 2002 and December 2003 and denied a second count of indecent assault on her.
He has denied a third count of sexually assaulting the girl.
He also denied indecent assault and a fifth charge of forcing her to have oral sex.
On the sixth charge, he pleaded not guilty to raping her when she was 12 and denied an alternative charge – of raping a child under 13 (under the new law when the act changed).
He also denied a seventh charge of raping her between December 2004 and December 2005 and denied an eighth count of rape – when she was 14 between August and December 2006.
Finally, he pleaded not guilty to sexually assaulting her on September 10 last year, by intentionally touching her breast.
