A married PC used a "secret" phone app to have an affair with the woman he is accused of murdering, a court heard.

PC Timothy Brehmer, 41, allegedly strangled lover Claire Parry in a pub car park after she threatened to tell his wife about their relationship.

Jurors have now heard how Brehmer arranged meetings with mum-of-two Claire, 41, through chat program Telegram.

More details of their affair were revealed on Monday as the defendant's police interviews were played in court.

Brehmer said: "We used to use WhatsApp but we changed to Telegram, it was hidden right at the back of my phone in the rubbish folder because I'm a devious bastard.

"I put her number hidden in the bottom of a note so I could dial it.

"She was in [Telegram] as Eric just because it was not her name. I didn't use it for anything else.

"One of the things was called a 'secret chat' on there, they expired after a while.

"It was always a secret app... it was Claire that found it and suggested we use it."

Dorset Police Constable Timothy Brehmer, 41

The Dorset Police officer said his meetings with nurse Claire offered "solace and excitement".

But despite their 11 year affair he never left wife Dorset Police DC Martha Brehmer, with whom he has a nine-year-old son.

He added: "I cared for her, I can't say I loved her because I didn't want to leave my wife, I loved my wife - she's brilliant and amazing."

Brehmer admits manslaughter but denies murdering Claire on May 9 this year in West Parley, Dorset.

During interview he told how she had broken the "unwritten rule" of affairs by demanding to know more about his "perfect" home life.

Brehmer said: "...all of a sudden she wanted to know all about my life.

"She got hold of my phone and looked through my messages, she wanted to see if I was talking to anyone."

Brehmer said that Claire sent a text reading "I'm cheating on you" to his wife after they met in his Citroen in a pub car park.

He added: "I tried to pull her out but she's quite strong, she leaned back in the car, lying across the gearstick.

"I piled into the passenger side to try to move her and push her, she turned away on her tummy.

"I managed to move her, I was lying across on her... I was trying so hard to pull her out the car.

"I don't know how long that went on for, she was trying to stay in the car.

"I managed to roll out of the door... I didn't look at her but she was not moving... I didn't mean to hurt her but I obviously have."

He added: "I never ever, for one nanosecond, intended to hurt her. I didn't strangle her, I didn't put my fingers around her throat or anything like that."

The trial at Salisbury Crown Court continues.
