After ABC/CBS initially suspended Thomas Gibson for kicking a producer, they have now decided to fire him and have terminated his contract.
Here is the statement from ABC Studios and CBS TV Studios:
“Thomas Gibson has been dismissed from Criminal Minds. Creative details for how the character’s exit will be addressed in the show will be announced at a later date.”
There also had been a previous on-set incident several years ago, when Gibson had to undergo anger management counseling after hitting assistant director Ian Woolf.
