A woman caused serious injury to her former partner in an attack at their Dorchester home – then went out to walk the dogs, a court heard.

Rachel Biscoe, 44, pleaded guilty at Weymouth Magistrates Court to inflicting grievous bodily harm (wounding without intent).

The court heard that on December 8 at Hessary Place, Poundbury, Biscoe caused serious injury to Trevor Camp, using an unknown object. He suffered an injury in the groin area.

Elizabeth Valera, prosecuting, said the defendant and Mr Camp were in a volatile relationship for six years. In a statement, Mr Camp said their relationship had changed after Biscoe discovered he had an affair.

“She found it hard to trust me and was suspicious of my movements,” he said.

On the day of the the offence, Biscoe came home from work to find Mr Camp on the bed on the phone to a female friend in China.

Biscoe accused Mr Camp of cheating and the pair moved to the kitchen where a ‘tussle’ over the phone began.

As Mr Camp was drunk at the time he said was not sure whether Biscoe had hit him in the groin area or used something to harm him.

He said he was exposed as he had no underpants on and wasn’t sure how the injury occurred but felt pain and saw blood.

He said: “Although we’ve had a volatile relationship, I really did not expect her to be so vicious.

The female friend remained on the phone and said to police Mr Camp had told her: “She got a knife and she sliced me.”

The victim had to have surgery and suffered an infection to the wound.

Ms Valera said Biscoe claimed the injuries were caused by the diamond engagement ring she was wearing when she grabbed him. The court heard Biscoe then left the injured Mr Camp to go and walk the dogs, an act chairman of the bench, William Gibbons, said was ‘rather callous’.

Aileen Tring, defending, said shortly after starting the relationship, Mr Camp had revealed he was a transvestite which Biscoe accepted, however, she added he had failed to reveal he was an alcoholic.

“She felt she wasn’t able to leave, and when he was sober he was a good person,” Miss Tring said.

Miss Tring added before the relationship Biscoe, who wept during the hearing, had led a blameless life and never troubled the courts.

“You can see the state of Miss Biscoe – she’s out of her depth.”

Biscoe, of Carnival Close, Ilminster, was handed four months in prison suspended for 12 months and a concurrent two months in prison, suspended for 12 months for breaching a conditional discharge from a previous assault conviction. She was ordered to undertake 20 rehabilitation activity requirement days, 160 hours of unpaid work and pay £300 compensation to the victim.
