A SPURNED violent Greenock thug was caught on a 999 call carrying out a brutal hammer attack on his ex-partner.

Christopher Jamieson, 40, smashed his way into the woman’s home in the town late at night after she ended their relationship and struck her with the hammer around TEN times.

During a terrifying 10-minute assault, he battered the victim with the tool, as well as punching, biting and choking her.

The woman immediately called the police upon hearing Jamieson bursting into her home.

The call remained connected during the attack.

Jamieson appeared in the dock at the High Court in Glasgow and pleaded guilty to assaulting his ex-partner to her severe injury, permanent disfigurement and to the danger of her life on February 8.

Prosecutor Alex Sutherland told the court that Jamieson had dated the woman for six months.

Advocate depute Mr Sutherland added: “He appeared unable to accept it was over.

“Prior to the incident, he had contacted her repeatedly by phone and text message."

The woman was in bed when she was awoken at around midnight by the sound of a glass panel in her back door being smashed.

The advocate depute said: “Fearing for her safety, she called 999 and made her way back to the bedroom.

"She then saw Jamieson at the top of the stair carrying a hammer. She was utterly terrified."

Jamieson threatened to kill the woman as he went after her, pinning her down on the bed and repeatedly punching her.

Mr Sutherland said: “Jamieson began to choke her using both hands around her neck.

"At one point, he held the handle of the hammer across her neck causing her to struggle to breathe."

Despite her managing to briefly break free, Jamieson sunk his teeth into the woman’s nose, arms and below her eye – unaware that that 999 call has been made and was still connected.

The recording of the call – in which the victim could be heard screaming for help - was played in court for Judge Lord Armstrong.

Jamieson told the woman she was ‘going to die’, and that he was going to ‘smash her face’ and ‘burst her skull’.

The court heard that police soon arrived to see Jamieson emerge from the bedroom claiming he was ‘giving himself up’.

Mr Sutherland said the victim’s injuries included fractures to her nose and hand, and that she continues to suffer pain and may need surgery.

The hearing was told she remains traumatised by what happened.

Jamieson has a history of violence and holds convictions from 2003, 2010 and 2011.

Lord Armstrong remanded him in custody and deferred sentencing until September to allow for the preparation of reports.

He also imposed a non-harassment order banning Jamieson from contacting the woman.
