Actor Edward Furlong has been charged with assault after a May 21 incident in which his girlfriend called police and reported he attacked her.
Deputy District Attorney Linda Loftfield says the Terminator 2 star pleaded not guilty at his arraignment.
Furlong already has two pending misdemeanour battery cases. He allegedly violated a restraining order when he returned to the victim's West Hollywood home.
He's also accused of damaging a laptop and photo equipment.
In March, the 35-year-old actor was sentenced to six months in jail for violating his probation in a 2010 case for violating a similar restraining order.
Furlong has been the subject of such orders taken out by both his ex-wife and ex-girlfriend.
He is being held on $100 000 bail.
A preliminary hearing is set for July 1.
