At least 200 people were arrested while 139 others were detained on Thursday, according to Turkish news agencies.
Police carried out the operations in 13 provinces across Turkey. With most of the arrestees being academics, those arrested over the past day also included teachers, state workers and military personal.
Among those detained are small business owners, housewives, state workers, lawyers, court personnel, teachers and doctors.
The Justice and Development Party (AKP) government, which launched a war against the Gülen movement following the eruption of a corruption scandal in late 2013 in which senior government members were implicated, carried its ongoing crackdown on the movement and its sympathizers to a new level after a failed coup attempt on July 15 that killed 240 people and injured a thousand others.
Although the movement strongly denies having any role in the corruption probe or the coup attempt, the government accuses it of having masterminded both despite the lack of any tangible evidence.
Turkish Islamic scholar Fethullah Gülen called for an international investigation into the coup attempt, but President Recep Tayyip Erdoğan — calling the coup attempt “a gift from God” — and the government initiated a widespread purge aimed at cleansing sympathizers of the movement from within state institutions, dehumanizing its popular figures and putting them in custody.
More than 100,000 people have been purged from state bodies, nearly 70,000 detained and 32,000 arrested since the coup attempt. Arrestees include journalists, judges, prosecutors, police officers, military personnel, doctors, court personnel and even a comedian.
