After the investigators requested the names of the individuals who were staying at the hotel room, five suspects were identified, with one of them currently in the Turkish Republic of Cyprus.
The investigators reportedly believe that one of these suspects might be the person who ordered the assassination of the Russian ambassador.
Andrei Karlov was shot and killed at an art gallery exhibition opening in Ankara on December 19. Three more people were injured in the shooting. The gunman was killed at the scene by the police. The Russian Foreign Ministry said it considered the attack a terrorist act.
