A doctor allegedly bludgeoned her husband to death with a hammer, fearing he would reveal they were having sex with a teenager.

Chamari Liyanage is accused of murdering Dinendra Athukorala, also a doctor, because she worried his unusual sexual proclivities could jeopardise her career, the Supreme Court of Western Australia heard.

She was fed up of being coerced her into threesome with other women, including a 17-year old girl with whom the Sri Lankan couple were having an affair, said prosecutor Nick Cogan, according to Perth Now.

“It got to a stage that she was no longer prepared to put up with his behaviour,” he added, the West Australian reported.

Dr Liyanage told police her husband was physically violent, forced her to engage in sexual acts and controlled her movements and finances.

The jury heard a tearful 10-minute call she made to triple-0 at 6.11am in June 2014, in which she said she could not remember what had happened.

Officers arrived at the unit in Geraldton, WA, at 6.18am and spoke to her as she sat in the foetal position by the bed.

Dr Athukorala’s body was lying on the mattress covered in blood, which had splattered over the wall and blinds above him, police said. A pillow was on top of the corpse, they told the court.

“I asked if she knew what had happened,” said Matthew Curley, one of the first officers on the scene. “She said she did not know.”

He said he also saw a mallet or hammer lying on the bed. When asked, a sobbing Liyanage said it belonged to her husband.

Defence lawyer George Giudice said his client was a “sleep-deprived, anxious, trapped and battered woman”. He said she was made to model for her husband in front of a camera, sometimes for hours on end.

Liyanage pleaded not guilty to murdering her husband. The trial, set down for three weeks, continues.
