Thomas Gibson’s suspension from Criminal Minds has been made permanent. The producers of the long-running CBS crime drama have moved to terminate Gibson’s contract following a physical altercation on the set of the show, produced by ABC Studios and CBS TV Studios, with ABC Studios running lead.

“Thomas Gibson has been dismissed from Criminal Minds,” the two studios said in a joint statement. “Creative details for how the character’s exit will be addressed in the show will be announced at a later date.”

Gibson had been suspended for 1-2 episodes (2 weeks) following the incident, which allegedly involved him kicking co-executive producer Virgil Williams. It happened two weeks ago but only came to light about 36 hours ago. There also had been a previous on-set incident in 2010 when Gibson had to undergo anger management counseling after hitting assistant director Ian Woolf. The decision to dismiss Gibson was made after a brief internal review, with the actor’s prior history, which also included a DUI arrest, taken into consideration.

Gibson is an original Criminal Minds cast member, playing Special Agent Aaron Hotchner since the series’ 2005 debut. He also directed 6 episodes of the show.

Gibson will appear in the first two episodes of the series’ upcoming 12th season, which he’d already filmed, but will do no more work on the show, with his character written off.

Criminal Minds returns for Season 12 on September 28. It features new regular Adam Rodriguez, who will help fill the void left by the departure of original cast member Shemar Moore at the end of last season.
