A 15-year-old girl camping with friends in her back garden was assaulted by a drunken man.

Blackburn magistrates heard that Christopher James Gregory turned up at the sleepover uninvited and started kicking the tent and shouting.

He grabbed the girl and pushed her against a wheelie bin.

Gregory, 18, of Markham Road, Blackburn, pleaded guilty to assaulting the girl and was ordered to do 50 hours of unpaid work.
