TMZ reported the development in the case Thursday.
Dekker was arrested last month for alleged drunken driving after police said he hit a 17-year-old bicyclist with his car near a freeway on-ramp in Los Angeles.
The teen was treated for minor injuries, TMZ noted.
Dekker, 21, is best known for his work on the recently canceled TV series "The Sarah Connor Chronicles."
