A man has admitted beating and stabbing his flatmate to death after she refused to have sex with him.

Gary Stevenson, 27, stabbed Katy Rourke, 25, at their shared flat in Govan, Glasgow, after the pair had been drinking.

Glasgow High Court heard that the pair had had sex after drinking vodka together but when Ms Rourke refused to have sex again, he started punching her.

Stevenson then got a knife from the kitchen and stabbed her three times, the court heard.

Stevenson admitted to the murder after travelling to North Berwick where he attempted to commit suicide by slashing his wrists.

He told investigators: "I lost control. I didn't think about the consequence of my actions. Once it started it just took off.

"She started kicking and stuff so I started punching her in the face.

"I tried to stop her moving but then she started shouting for help and stuff. I went into the kitchen to get a knife."

A post-mortem examination revealed a stab wound to Ms Rourke's chest had gone through her heart and she had suffered bruising, cuts and blunt force trauma to the head and face.

Presiding Judge Lady Rae has deferred sentencing till next month to allow time for background reports.

Detective Inspector Margaret-Ann May, the senior Investigating Officer on this case, said: "This was a very distressing case culminating in the death of a bright, popular young woman with her whole life ahead of her.

"A diligent and through investigation by the major investigation team lead to Gary Stevenson admitting his guilt today, and I am glad that this has spared the family the trauma of a trial.
