Oklahoma City Thunder center Enes Kanter tweeted on Friday that his father, Mehmet, has been arrested by the Turkish government.

Kanter, who is from Turkey, has been a vocal critic of president Recep Tayyip Erdoğan, calling him the "Hitler of our century."

Details of the alleged arrest are unknown, but a Turkish newspaper reported last week that a warrant was issued for Kanter's arrest in Turkey and Kanter previously was detained at a Romanian airport because Turkey had canceled his passport.

Kanter is a supporter of Fethullah Gulen, an Islamic preacher who has lived in self-imposed exile in Pennsylvania since 1999. The Turkish government blamed Gulen for an attempted military coup last summer.

According to ESPN, Kanter said recently that he hasn't spoken to his father in two years. Mehmet told a Turkish newspaper last summer that the family "disavowed" Kanter for his support of Gulen.
