Dink was killed outside his paper, Agos, in Istanbul in January.


Prosecutors have pressed charges against 10 suspects, including some former members of the youth wing of Great Unity.


According to NTV, police were still looking for another leading member of Great Unity, Halis Egemen.


Dink's killing prompted international condemnation as well as debate within Turkey about free speech, and whether state institutions were tolerant of militant nationalists.
