Lou Diamond Phillips has been arrested in Los Angeles on a charge of domestic battering.
If convicted, the 'Young Guns' and 'La Bamba' star faces a one-year jail sentence as well as a $2,000 fine.
He is accused of injuring his girlfriend on August 11th, when the couple argued and he allegedly dragged her around the house.
According to court documents, this resulted in scrapes on her knees, before she phoned police from the bathroom, where she locked herself in.
Phillips was arrested for the incident before being released on bail.
The 44-year-old's arraignment is due to take place on October 18th.
