Los Angeles - Edward Furlong was arrested on Tuesday after allegedly violating a court order to stay at least 100m away from his estranged wife.
The Green Hornet actor - who is the subject of a three-year restraining order forbidding him from going near Rachael Bella at her home, place of work and vehicle - was taken into police custody after turning up to court for a progress report. In the report it was found that, according to the Los Angeles City Attorney's Office, Edward breached the order last month by coming within 50m of Rachael.
The 33-year-old star - who has a four-year-old son, Ethan, with Rachael - was then sent to jail, before being released after posting his $75 000 bail.
A probation violation hearing has now been set for February 14.
The restraining order came after Rachael - who filed for divorce from Edward in July 2009 after three years of marriage - told the court in a previous hearing the actor repeatedly drives past her house, once threatened to kill himself and refused to take a drug test when she demanded he take one during their custody dispute.
Edward - who shot to fame aged 13 - has a history of alcohol and substance abuse problems and has had several stints in rehab.
He was arrested twice in 2001, for driving without a license and driving under the influence and again in 2004 when he tried to free lobsters from a restaurant in Kentucky, where he was filming Jimmy and Judy.
