Former Istanbul Police Chief Hüseyin Çapkın surrendered himself to police after a court issued arrest warrant against him as part of an investigation into the Gulen movement.

Çapkın, who served as İstanbul chief of police between 2009 and 2013, was detained in the western province of İzmir on Aug. 31, 2016 as part of an investigation launched by the İstanbul Chief Public Prosecutor’s Office into the attempted coup. He was released in November.

The indictment seeks three consecutive life sentences for Çapkın along with former İstanbul Governor Hüseyin Avni Mutlu, who are charged with “violating the Constitution, membership in a terrorist organization and attempting to abolish the government of the Republic of Turkey and the Parliament through violence.”

The government accuses the movement of masterminding the July 15 coup attempt. Some 120,000 people have been detained and 50,000 people have been put under arrest over alleged or real ties to the movement since the coup bid.
