Polymer engineering professor Hüseyin Yıldırım and four people, who all used to work at the Yalova University were detained as part of an investigation into the Gülen movement on Friday.

The suspects are accused of having made donations to the movement, state-run Anadolu news agency said.

The government earlier removed them all from their jobs with a post-coup emergency decree, Anadolu added.

Turkish government blames the movement for leading the failed putsch in the summer of 2016, a claim the group denies.
