Special Activities Division

Special Activities was a division within the Central Intelligence Agency (CIA) responsible for interrogation and covert operations. There was a Special Activities unit operating at the CIA London station.

A few days before Day 9, Chloe O'Brian was captured by Special Activities and held in their facilities. O'Brian was subject to intense questioning and torture during that time. Somehow, fugitive Jack Bauer found out about Chloe's capture, and managed to get himself captured on purpose. Knowing his status, the President's Chief of Staff Mark Boudreau ordered CIA Head of Station Steve Navarro to transfer Bauer to Special Activities.

When Bauer was about to be transferred, he managed to knock out the agents escorting him and infiltrated the Special Activities basement. Jack threatened Dean forcing him to take him to Chloe, where he freed her. Despite Kate Morgan's attempt to stop them, Bauer escaped with the aide of Belcheck.
