Thomas Dekker, the actor who played John Connor in the Terminator TV series, has been charged with two counts of driving under the influence (DUI).

The 21-year-old was arrested last month after allegedly crashing his car into a 17-year-old cyclist near a freeway on-ramp.

Dekker was allegedly drink-driving at the time of the incident and has been charged with two misdemeanour counts of DUI.

The Nevada-born actor was arrested and bailed from an LA jail, but will be arraigned later this week.

The victim was treated for minor injuries.
