Edward Furlong is currently being held on $50,000 bond.
The Terminator 2 actor, 35, was arrested Tuesday after allegedly grabbing his girlfriend's arm, E! News reports.
The incident occurred at Los Angeles International Airport, and airport police said in a statement, "On Oct. 30, 2012 at approximately 12:40 a.m., Los Angeles Airport Police officers responded to a call regarding a possible domestic violence investigation at Terminal 2 on the arrivals level."
This isn't Furlong's first run-in with the law. The actor, who has had a long history of alcohol and drug addiction, allegedly punched his now ex-wife Rachel Bella in September 2009 during a fight. He was arrested in January 2010 for violating his probation stemming from a restraining order his ex filed.
Furlong is father to son Ethan, 6, with Bella. In January 2011 he told a judge he couldn't pay child support because he was "completely broke."
