Turkish authorities have ordered the arrest of 105 people working in information technology who were believed to have been involved in the attempted military coup a year ago, state-run Anadolu news agency reported on Tuesday.
In the last year, there has been a steady stream of police operations targeting people suspected of links to the U.S.-based Islamic cleric Fethullah Gulen, whom Ankara accuses of orchestrating the failed putsch on July 15.
Police have so far detained 52 people out of the 105 targeted by arrest warrants across eight provinces, including former staff from Turkey’s scientific research council TUBITAK and a telecommunications authority, Anadolu said.
It said the suspects were believed to be users of ByLock, an encrypted messaging app the government says was used by Gulen’s followers. Gulen has denied involvement in the attempted military takeover.
On Monday, Turkey issued arrest warrants for 72 university staff, including a former adviser to the main opposition leader who staged a mass rally on Sunday to protest against a crackdown in the last year.
About 50,000 people have been arrested and 150,000 state workers including teachers, judges and soldiers have been suspended under emergency rule imposed in late July.
Rights groups and government critics say Turkey has been drifting toward authoritarianism for years, a process they say accelerated since the coup bid and a referendum in April granting President Tayyip Erdogan sweeping new powers.
The government says the crackdown and constitutional changes are necessary to address security threats. More than 240 people were killed in the coup attempt.
