A drunk forced his way into his sister’s home, sank his teeth into her boyfriend’s back and “shook his skin like a dog”.

Victim Gareth Huckle suffered severe bruising as he fought to keep Matthew Foster out of the flat in Margate.

Now Foster, 27, of the town’s Addington Road, has been given a four-month jail sentence to run consecutively to a term he is already serving for a previous assault.

Canterbury Crown Court heard how his sister told police: “My brother has been an alcoholic for quite a time and arrived at my home drunk, as usual, at 5.30am.

“He was all over the place and was gritting his teeth when he talked. He has been violent to me and my family, particularly when he is drunk. I wasn’t prepared to let him in as I have two small children.”

Foster then swore at his sister before punching the front door and then punching Mr Huckle and headbutting him.

The court heard that while Mr Huckle was being held in a headlock, Foster bit his back.

His sister said: “I was screaming for him to stop. He sunk his teeth in and then pulled the skin and shook his head from side to side like a dog.”

Kerry Waitt, defending, said Foster now wanted to apologise and “having had time to reflect is now thoroughly ashamed of his behaviour”.

Foster, who admitted the assault, is already serving a 38-month sentence after robbing the long-term partner of his late grandfather after accusing her of stealing his inheritance.

During the incident he snatched a necklace and ring after threatening to break his terrified victim’s fingers “one at a time”, all while being on a suspended sentence for attacking his mother.
