Prosecutors in Istanbul on Tuesday, October 6, ordered the arrests of nine people suspected in the murder of Turkish-Armenian journalist Hrant Dink, Daily Sabah reports.

Dink was one of the founders of the bilingual Turkish-Armenian Agos newspaper and was killed outside his office in Istanbul on January 19, 2007.

His murder sparked widespread protests and led to speculation about the involvement of far-right groups and claims of a cover-up.

Ogun Samast, who was aged 17 years at the time of the killing, was jailed for 23 years in 2011. He claimed he killed Dink for “insulting Turkishness.”

An earlier investigation showed that the prosecutors who worked on the case ignored serious allegations of the involvement of top police officers in the murder.

The prosecutors are accused of having ties with the Gülen Movement, a group whose widespread infiltration of the judiciary and police enabled them to influence cases or fabricate them for their own interests.
