Three dismissed police chiefs and a university students were detained near Turkey’s Kapikule border gate with Bulgaria on Wednesday.

The four people were detained in a military zone in Turkish part while they were reportedly on their way to escape Turkey’s post-coup crackdown to Bulgaria.

According to state-run Anadolu news agency, the detainees had outstanding arrests warrants earlier issued against them over links to the Gulen movement.

The government accuses the movement of masterminding the July 15, 2016 coup attempt and has detained more than 120,000 people in its crackdown since then.
