Actor Thomas Dekker has been arrested in California on suspicion of driving under the influence (DUI) after allegedly running over a cyclist.

The 21-year-old star, who played John Connor in TV series Terminator: The Sarah Connor Chronicles, was busted on Wednesday night 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.

The Terminator TV show was cancelled earlier this year after just two seasons.
