Sixty people have been detained in as many as 14 cities for alleged links to the Gülen movement, a faith-based group outlawed by Ankara, the Stockholm Center for Freedom reported, citing Interior Minister Ali Yerlikaya said on Thursday.
Detention warrants were issued as part of an investigation into an alleged network affiliated with the movement.
The police seized more than 170,000 euros in cash and other valuables during house raids conducted as part of the operation.
Turkish President Recep Tayyip Erdoğan has been targeting followers of the Gülen movement, inspired by Turkish Muslim cleric Fethullah Gülen, since the 2013 corruption investigations, which implicated then-prime minister Erdoğan, his family members and his inner circle.
Dismissing the investigations as a Gülenist coup and conspiracy against his government, Erdoğan designated the movement as a terrorist organization and began to target its members. He intensified the crackdown on the movement following an abortive putsch in 2016 that he accused Gülen of masterminding. Gülen and the movement strongly deny involvement in the coup attempt or any terrorist activity.
In addition to the thousands who were jailed, scores of other Gülen movement followers had to flee Turkey to avoid the government crackdown.
