The 21-year-old star, who played John Connor in TV series Terminator: The Sarah Connor Chronicles, was busted on Wednesday night (14Oct09) in the San Fernando Valley after the accident was reported to police.

He is being held on suspicion of felony DUI and causing bodily harm and his bail has been set at $100,000, reports TMZ.com.
