At least 20 of eighty university students who were detained by Ankara police last week, were put in pre-trial detention on Wednesday over alleged links to Gulen group.
Özer was the deputy chief physician at Ankara Nallıhan State Hospital. He was sent to prison after a coup attempt in 2016 on terror and coup charges. Some two years later, his son, Miraç Özer, was sent to prison over similar accusations.
Turkey survived a military coup attempt on July 15 that killed over 240 people and wounded more than a thousand others. Immediately after the putsch, the Justice and Development Party (AKP) government along with President Recep Tayyip Erdoğan pinned the blame on the Gülen group.
The group denies any involvement. Thousands of people arrested on coup charges and membership in the group so far.
