In his statement right after the shooting, T.Ö. had also said they thought Altıntaş was an official bodyguard before the killing took place.
Altıntaş was shot dead by police at the scene while he was delivering a speech after shooting Karlov.
The police officer, meanwhile, is suspected of protecting Altıntaş at the police department where he used to work.
Ambassador Karlov was shot dead on Dec. 19, 2016 by Altıntaş, who entered the gallery with his police ID and was standing behind the victim at the time of the assassination.
