A MAN punched his partner before smashing up her car with a hammer after an early morning row, a court heard.

Jamie Moloney, of Graham Road, Birmingham, denies one count of burglary and another count of assault by beating.

Oxford Crown Court heard at the start of his trial yesterday how the 29-year old had already admitted another count of causing criminal damage relating to the violent episode on January 3 this year.

Outlining the case before a jury panel of seven women and five men prosecutor Stuart Dingle said that Moloney had been staying with his then-partner at an address in Bicester before the attack.

He said that a row broke out which led to Moloney 'shouting' at his victim before 'becoming abusive towards her.'

Jurors were told that Moloney then assaulted the woman before leaving the house to find a hammer, which he used to smash all of the windows on the woman's car.

Prosecutors claim that after leaving the house he later came back before smashing his way inside and stealing an iPhone.

Taking to the witness box yesterday the alleged victim told jurors the row started after a friend of hers arrived making noise, and waking up Moloney at about 1am.

She told jurors: "[Moloney] said 'if I can't sleep, no one can sleep.' He jumped out of bed, turning taps on, put the loud music on, shouting.

"I didn't respond, I went and asked my friend if he would like to leave the house because it would just escalate further if he didn't."

She said that after her friend left the house Moloney carried on shouting before he 'pushed me into the wall and hurt my arm'.

As things escalated, jurors were told, she called police and Moloney said 'if that is the police I will end you' before he launched into violence.

The alleged victim described Moloney smashing her phone on the floor before punching her in the face.

Jurors were told that he then left the house before using a hammer to smash all of the windows of the woman's car before leaving.

Later, prosecutors claim, he came back to the house for his belongings and while she was in another bedroom he 'smashed' his way inside before stealing an iPhone.

The alleged victim said that she had suffered no major injuries from the violence but had been left feeling sore.

The court heard that Moloney was later arrested by police and went on to deny the charges.

The trial continues.
