A CAM man who smashed a tea mug into another man's face during a drunken gathering in a Stroud house was jailed for 13 months today.

After scarring Tyrone Drew badly with the mug, Shane Fraser was taken home by police - only to return to the house later and assault another man there, Gloucester Crown Court was told.

Fraser, 20, of The Crofts, admitted unlawfully wounding Mr Drew and common assault on Benjamin Connor on April 2 this year.

Prosecutor David Maunder said the offences happened at the home of Kim Jones, 21, of Arundel Mill Lane, Stroud.

She was there with several friends including the defendant and the victims that night, Mr Maunder said.

He told the court that Fraser had once had a brief relationship with Miss Jones but at the time of the offence Tyrone Drew was her boyfriend.

When Fraser arrived at the house he was sober and in good spirits but there was then heavy drinking and 'the atmosphere became rather more aggressive,' said the prosecutor.

"What provoked the violence is a matter of some difference of opinion among witnesses. Mr Drew says the defendant was holding a vodka bottle by the neck and swinging it around.

"He threw it, causing it to smash on the floor. Luke called the defendant an idiot or similar, to which the defendant replied 'Why are you calling me an idiot - I'll smash your face in.'

"He moved across the kitchen and picked up a china mug. He moved back to Drew, pushed him in the chest against the back door and smashed the mug into the left side of his face."

Mr Maunder said it was obvious that Mr Drew was badly injured because he was bleeding heavily. He had a wound down the left side of his face from the top of the ear 10cms long which later needed 14 stitches.

Police were called and saw glass and blood around the house and found all the parties making 'accusatory remarks.' Officers did not arrest anyone at that time and they took Fraser home.

But later Fraser returned to the house and threatened Ben Connor with a large shard of glass as well as spitting at him and putting a lighted cigarette to his hand, the prosecutor alleged.

Fraser was arrested a week later on April 9.

Mr Maunder said Fraser had made five previous court appearances.

Joe Maloney, defending, said that Fraser now had his life on track with a girlfriend, a new home together with her, and he had been abstinent from alcohol for three months.

However, he said, Fraser was realistic about his situation and realised custody was likely. It had been a case of 'booze in, brains out,' that night, he added.

Sentencing Fraser to 12 months' custody for unlawfully wounding Mr Drew and a month consecutively for assaulting Mr Connor, Judge Jamie Tabor QC told him: "When you drink far too much you turn into a very unpleasant person who, I suspect, would be unrecognisable to those who see you when you are sober."
