The Terminator 2: Judgment Day star was detained after cops arrived at a Los Angeles residence in response to a ""boyfriend/girlfriend disturbance,"" authorities tell E! News.
The website reports Furlong allegedly shoved an unnamed woman and was taken into custody at Men's Central Jail and held on $50,000 (£31,250) bail.
Cops had an outstanding warrant for his arrest, stemming from a previous domestic violence incident.
He is due to appear at the Beverly Hills Courthouse on Tuesday (15Jan13).
Furlong was arrested twice last year (12) on suspicion of harming his lover - in October (12) following a bust-up at Los Angeles International Airport, and again the following month (Nov12) after an alleged fight at the couple's home.
