A man engaged in a romance with a married Policewoman claims her husband attacked him with a knife.

Gregory Campbell, 31, was in bed with Ceblle Dawson when her estranged husband, Thisley Dawson nicknamed Thunder arrived at her Sandys home.

According to Mr. Campbell, Dawson chopped him with a knife "almost twelve inches long", leaving him with wounds to his head, arm and hand.

Dawson, 42, is now on trial at Supreme Court accused of wounding with intent to do grievous bodily harm over the incident at 10.45 p.m. on May 25, 2009.

Mr. Campbell, a Jamaican living in Pembroke, told the jury he'd known Mrs. Dawson for 18 months. He knew she was married, but explained: "First we were good friends, before we got romantic."

Mr. Campbell said Mrs. Dawson lived alone with her two children and he never saw her husband during multiple visits to her home when he stayed "all night, all day".

On the night in question, he said he was lying down in her room when he heard someone breaking into the house. He woke up Mrs. Dawson and she went to the living room.

Mr. Campbell went to the kitchen, but heard Mrs. Dawson warn her 11-year-old son: "Run back to your room because Thunder has a knife."

Next, he said: "Then she run back to her room, closed her door and I went outside. I was outside, then Mr. Dawson come outside and attacked me with a long knife strike me on my head, chopped me open."

This left him with an injury to the left side of his head.

"Then I run across the street to a neighbour house. He was chasing me across the street," added Mr. Campbell, who explained: "I was running for my life."

He said Dawson caught him and chopped him four more times, to the left side of his head, his right wrist, his left thumb and his left shoulder while asking him who he was.

The knife eventually fell out of Dawson's hand, and Mr. Campbell ran to Somerset Police Station, where an ambulance was called to take him to hospital. He remained there for two days, and required stitches and staples to his wounds.

Dawson was arrested outside the house later that night, and a kitchen knife was seized from the kitchen sink by Police.

Police Sergeant Emmerson Donald told the court he overheard Dawson at Somerset Police Station after his arrest saying: "I should have killed him. He slept with my wife."

Under cross-examination from defence lawyer Kenrick James, Mr. Campbell insisted that the first time Dawson saw him was outside the house, and he did not catch him in bed with his wife.

However, Mr. James put it to him that Dawson actually entered the premises with a key rather than breaking in.

"Mr. Dawson came into the bedroom, met you and Mrs. Dawson in a compromising position, and in a state of shock he kept asking 'who are you, who are you'?" said Mr. James.

"And in the meantime you got up and managed to put on some trousers and you sprang an attack on Mr. Dawson."

Mr. Campbell responded: "That's not true. If Mr. Dawson saw me in the bedroom with Ceblle I would be a dead man today."

Mr. James went on to allege that what happened was a struggle and a fight between the two men, but Mr. Campbell insisted: "It was not a struggle, not a fight, it was an attack."

Mr. James claimed Mr. Dawson moved out of the house in mid-February 2009, but moved back in with his wife around March 19 of that year.

Mr. Campbell said he did not know anything about that. However, he told the court Mrs. Dawson moved in with him after the incident "because the kids were having bad dreams at night".

According to Sgt. Donald, Mrs. Dawson was a reserve Police officer at the time of the incident, and training to become a full-time officer.

Dawson, whose bail address is listed as Fisherman's Hill, Hamilton Parish, denies the charge, and the case continues.
