CBS working on third CSI spin-off

US broadcast channel CBS is prepping a third CSI spin-off, this time focusing on a Virginia-based cyber crimes unit.

Anthony Zuiker croppedThe currently untitled series comes a decade after the original CSI series launched on the Eye Network and will join a family of programmes that also now includes CSI: Miami and CSI: MY.

It will follows a team of cyber crime FBI investigators in Quantico, Virginina, which represents the first time a CSI series has not focused on forensic investigation. It is based on the work of cyber psychologist Mary Aitken, who will be a producer.

CSI creator Anthony Zuiker is writing the spin-off along with showrunner Carol Mendelsohn and ex-CSI: Miami showrunner Ann Donahue. CBS Television Studios is producing alongside Bruckheimer Television.

Mendelsohn, Zuiker and Donahue will executive produce alongside Jerry Bruckheimer and Jonathan Littman.

The original CSI is currently in its 14th season, while CSI: Miami and CSI: NY ran for ten and nine seasons respectively.
