A DRUNKEN teenager sent to his room responded by going on the rampage with a Samurai sword.

Hyndburn Magistrates heard that in the same incident Michael Horrocks, 18, urinated down the stairs at the family home in Paxton Street, Accrington.

Horrocks admitted committing an affray and assaulting his mother, Beverly Horridge after drinking with friends to celebrate his sister's birthday.

The court heard how Mrs Horridge had asked her son to go upstairs when he became abusive, thought to be caused by the alcohol he was consuming.

The family sat down for their evening meal before Horrocks was said to have began drinking vodka, playing loud music and becoming unruly.

Mrs Horridge asked if the music could be turned down which, the court heard, started off the series of events that led to her son's arrest earlier this month.

Horrocks, swearing at his mum, was accused of biting her shoulder after punching holes in his bedroom door when he was sent to his room.

The court was told the youngster then took out a Samurai sword and began swinging it in the air taking chunks out of the bannister.

The youngster was then alleged to have told his mother that if she contacted the police he would have her house burned down and threatened to hurt her.

Phillipa White prosecuting said: "Police reported a clear bite mark. And when leaving her house he again threatened to burn it down.

"His friend was even in the loft fearful for his own safety."

Gary Price, defending, said: "Mr Horrocks has no recollection of biting his mother's shoulder. He admits he was intoxicated. But he accepts her series of events. And he should be given credit for that. He could have pleaded not guilty and made his mum give evidence. He spoke to alcohol counsellors and recognises he has a problem with alcohol."

Horrocks was remanded in police custody until he is sentenced at Crown Court at a date yet to be set.
