Edward Furlong ARRESTED Again -- Stay Away From Your Ex-GF!!!

"Terminator 2" actor Edward Furlong was arrested yet again last night -- after cops say he blew off a restraining order ... and got into a verbal altercation with his ex-GF, TMZ has learned.

Law enforcement tells us ... Furlong's ex-girlfriend called police and told officials Ed was at her West Hollywood home.

When cops arrived at the pad, we're told they found 35-year-old Furlong hiding under a stairwell near her residence.

Furlong was eventually taken into custody for violating the restraining order (a felony) -- which was initially issued against him after he was arrested (twice) for roughing up the ex-GF.

Furlong is currently being held on $100,000 bail.
