PALM SPRINGS, Calif. —  "CSI" co-star Gary Dourdan has been charged with felony possession of heroin, cocaine and ecstasy stemming from his arrest last month, prosecutors said.

The 41-year-old actor was arrested after police found him asleep in his car in Palm Springs on April 28. He was allegedly parked on the wrong side of the street with the car's interior light on.

Prosecutors said Dourdan is scheduled to appear in court in Indio, about 130 miles east of Los Angeles, on May 28. The criminal complaint was dated Tuesday.

A call to Dourdan's attorneys wasn't immediately returned early Thursday.

Dourdan has played crime scene investigator Warrick Brown on CBS' "CSI" since 2000.

Several celebrities were in Palm Springs for the Coachella Valley Music and Arts Festival in nearby Indio.
