Detention warrants were issued for 9 people who worked at the Undersecretariat for Treasury until they were dismissed over links to the Gulen movement, on Wednesday.

A tenth individual is also wanted in the investigation

Ankara Public Prosecutor’s office issued the warrants and four were rounded at the time of writing, state-run Anadolu news agency said.

Some of the suspects are accused of using ByLock mobile app that the government claims to be the top communication tool among Gulenists.

Turkish government holds the Gulen movement responsible for the July 15, 2016 coup attempt while the latter denies involvement. More than 150,000 people have been detained over ties to the movement in Turkey while 80,000 of them were remanded in prison pending trial so far.

Some 150,000 people have lost their jobs over similar reasons and more than 3,000 schools, dormitories and universities were shut down.
