BIRTHDAY celebrations spiralled out of control when a son launched a savage, short-lived attack on his father after returning from a night in Wetherspoon’s.

Martin John Wilkinson had been out drinking for his 30th birthday in Redcar town centre with his dad, and his dad's partner on January 20 before the night descended in carnage.

Wilkinson bit his father’s head during the melee and fractured his jaw before punching his father’s partner in the face as she attempted to stop the violent assault in their own home.

The 30-year-old, of Wilton Avenue, Redcar, appeared at Teesside Crown Court via video link from Durham Prison on Tuesday to be sentenced for common assault and wounding with intent.

Sam Faulks, prosecuting said they had all been out drinking in the town centre pub to celebrate Wilkinson's birthday.

On the way home they picked up a bottle of vodka to continue the celebrations but they soon ended up in violence.

“The defendant attacked his father and clawed at his face and bit the top of his head," he said. "His father felt the defendant's teeth sink into the top of his skull. He also latched onto his lip with his teeth and bit."

In mitigation, Paul Green, defending, said the assault was not a "prolonged attack" and was "over in seconds".

Judge Paul Watson QC heard how the father had forgiven his son for the violent attack.

Sentencing Wilkinson, the judge said: “"For no reason that anybody could see you launched into a brutal and unprovoked attack on your father.

"You were well under the influence at the time. The attack was a dreadful one".

Wilkinson was jailed for four years and six months.
