The Associated Press (h/t ESPN.com) cited the private Dogan news agency, noting university professor Mehmet Kanter was released after five days in custody as long as he consistently reports to a police station.
"He was detained as part of an investigation into alleged links to U.S.-based cleric Fethullah Gulen, according to media reports," the AP wrote.
This comes after Kanter tweeted about the situation Friday:
According to ESPN.com, Kanter is a known critic of Turkish president Recep Tayyip Erdogan. The AP noted Kanter is also "a supporter of Gulen, who the Turkish government blames for a failed military coup last summer."
The Daily Sabah (h/t A.J. Perez of USA Today) recently reported a warrant was issued for Kanter's arrest in Turkey for his alleged involvement in a terrorist organization that opposes Erdogan.
The six-year NBA veteran tweeted a video on May 20 saying he was being held at a Romanian airport because Turkey cancelled his passport for his political beliefs:
As for his father, Mehmet, the AP said he previously disowned his son because of his support for Gulen.
