Gary Baty, 21, of no fixed address, appeared for sentence at Chester Crown Court for breaching an Anti-Social Behaviour Order imposed on him in 2005.

The order banned him from going within 100 metres of his father's home in Mill Court, Pooltown Road, Ellesmere Port.

But on a succession of dates Baty had been seen at the Mill Court facilities which cater for people with mental health conditions.

Baty was also sentenced for assaulting his father, William Baty.

Peter Hussey, prosecuting, said on April 30 Baty turned up at Mill Court at 11.30pm with a bottle of cider.

"He demanded access to the premises and threatened to hit him if he didn't allow him in," Mr Hussey said.

"They drank, they argued and as a result the defendant attacked Baty senior by punching him.

"He cried out and this was heard by a neighbour who witnessed the defendant punching him to the head, body and stomach.

"The defendant was pushed outside the premises and continued to shout and swear and was aggressive, banging hard on the door and demanding he go back in."

Mr Hussey said police officers arrived shortly after and Baty admitted the assault but said it was in retaliation of being hit himself.

"He showed a complete lack of remorse and showed triumph for past assaults on William and made it clear he hates him," Mr Hussey said.

The ASBO was half way through five years and Baty had breached it 18 times, Mr Hussey said.

"The defendant has been in custody on three occasions."

Nicholas Williams, defending, said: "He may appear to be someone who has a disregard for court orders but it's not an entirely fair picture that has been painted.

"There is no sense of triumph and, looking back, he is upset he's in court for assaulting his father who he is in an ongoing relationship with.

"There is no particularly bad blood between them."

Mr Williams told the court the reason Baty went to see his father was because he was living in a tent and wanted somewhere warm to stay.

Judge Roger Dutton sentenced Baty to three years in prison for breaching the ASBO and four months in prison to run concurrently for assaulting his father.

He said: "You're completely unable and unwilling to comply with the ASBO to protect your father.

"It's clear you have got an alcohol problem.

"You have got a problem with your lifestyle and have been unable and unwilling to sort your life out but continually assault your father and make his life a misery.

"There will be no more pussy-footing around."

Judge Dutton told Baty he would serve half of the sentence in prison and the other half under supervision in the community.
