ANKARA, Turkey -- The father of Oklahoma City Thunder center Enes Kanter has been released from police custody in Turkey, where he was detained as part of an investigation into alleged links to U.S.-based cleric Fethullah Gulen.

Enes Kanter confirmed to ESPN that his father -- university professor Mehmet Kanter -- was released Wednesday after five days in custody on condition that he regularly report to a police station.

Enes Kanter is a vocal supporter of Gulen, who the Turkish government blames for a failed military coup last summer. Mehmet Kanter had disowned his son for his open support of Gulen.

Enes was detained in Romania on May 20 because his Turkish passport was cancelled. He said he was able to return to the United States after American officials intervened.
