Tom Sizemore -- Arrested for Domestic Violence

Tom Sizemore has just been arrested for allegedly beating up his girlfriend ... TMZ has learned.

Law enforcement sources tell TMZ ... LAPD received multiple 911 calls Tuesday morning about a woman screaming. When cops arrived ... his girlfriend said she and Tom got into an argument that turned physical, and Tom struck her in the head and face.

We're told cops saw visible injuries ... but she refused medical attention.

The arrest comes 2 weeks after Tom accidentally ran over a stuntman while filming a TV show north of Los Angeles.

Tom was booked for felony domestic violence. As of this post he's still in custody with bail set at $50,000.

Sizemore has a record of domestic violence. He was sentenced to 6 months in jail back in 2003 for beating up then-girlfriend Heidi Fleiss.

We reached out to Tom's rep, so far no word back.
