Radko was one of Karl Rask's henchmen during Day 9. When Jack Bauer arrived at Rask's hideout at around 4:30pm, he told him and his men that he had brought the CIA agent to whom Nils was ratting them. When Jack told them she was unconscious because of a dose of propofol, Rask told him that they had something to counter the effects. He then instructed Radko and Danilo to get Morgan out of the trunk, awaken her, and interrogate her.
