A WOMAN who claims she was sexually assaulted after a barbecue party went after her alleged attacker with a knife and put him in hospital, a jury has been told.

The woman, who cannot be named for legal reasons, was arrested by police who were called to the scene at a house in Bewdley after they saw Adam Parsons lying on the driveway with a stab wound that had damaged his spleen and caused his lung to collapse, Worcester Crown Court heard.

He spent eight days in hospital after the incident on July 6 last year and was charged with two sex offences, Simon Phillips, prosecuting, told the court. The woman has been charged with wounding and has yet to appear in court.

Parsons, aged 33, of Queensway, Bewdley, is on trial after pleading not guilty to sexual assault and assault by penetration.

Mr Phillips told the jury Parsons and another man were to stay the night after the barbecue in the same house as the woman, who is in her 20s, and her husband.

They had all been drinking and after an argument with her husband, she went to bed while he went out for a walk, Mr Phillips said.

She was woken up shortly afterwards by Parsons in her bedroom kissing her and sexually assaulting her.

"I was very scared," she said. "I froze and pretended to be asleep."

Parsons, she said, was talking to himself, saying what he was doing was wrong and also about how he wanted to kill people.

He got off her bed and went downstairs when the front door opened and her husband came back to the house, she said. She got dressed and went downstairs "screaming and shouting" in a rage at Parsons, the jury heard.

"I was angry. I told him he was a rapist," she said. She told him to leave and when he refused, she pushed and punched him to get him outside. She also grabbed a knife used during the barbecue and stabbed the wall with it to show her anger, breaking off the end of the blade.

Martin Butterworth, defending, said Parsons told her he didn't know what she was talking about. He tried to protect himself but did not fight back. They went outside onto the driveway and he suffered a stab wound which caused him to fall to the floor with a collapsed lung. She agreed she had fallen on top of him, still punching him in the face, though she said most of the blows hit the floor.

She denied a suggestion by Martin Butterworth, defending Parsons, that she had exaggerated the sexual assault to use as a defence when she appears in court to face a charge of causing grievous bodily harm.

Parsons said the woman had been making advances to him.

The trial is expected to last until the end of the week.
