Police in Turkey detained Wednesday a fresh suspect in an ongoing investigation over the killing of Russian ambassador in Ankara, according to a security source.
The suspect, identified only by his initials as E.B., was accused of having phone calls with Andrey Karlov's assassin, police officer Mevlut Mert Altintas, the source said on condition of anonymity due to restrictions on talking to the media.
Police had earlier detained three other suspects, including a police officer.
Karlov was shot Dec. 19, 2016 by Altintas as the diplomat delivered a speech at an art exhibition in the Turkish capital.
Altintas was later shot dead in an exchange of fire with security personnel.
