CBS casts more 'NCIS' spinoff leads

Louise Lombard, Peter Cambor and Daniela Ruah have been cast in CBS's NCIS spinoff, reports The Hollywood Reporter.

British actress Lombard, who previously starred in CSI: Crime Scene Investigation, will play Clara, a former major in the military police who is described as being an "intelligent, sharp investigator".

Cambor will star as Nate, an operational psychologist and expert on American culture, while Ruah will play a young investigator named Kensi who has a speciality in forensics and criminology.

The three actors are set to appear alongside Chris O'Donnell and LL Cool J, who are reportedly still in negotiations to join the naval investigation drama.

The new characters will be introduced through an episode of NCIS later this year.
