Petersen to quit CSI drama after eight years

ACTOR William Petersen is to leave CSI: Crime Scene Investigation, having been with the TV forensics drama since its first episode eight years ago.

He will still make guest appearances as Gil Grissom but his character will no longer be seen on a regular basis, two of the show’s executive producers said.

His final episode is likely to be broadcast early next year as part of the programme’s 10th series.
