According to Deadspin, the chief prosecutor in Istanbul filed an international arrest warrant for Enes Kanter.
The prosecutor's office officially charged Kanter with charges of supporting a terrorist organization.
Kanter is a center for the New York Knicks, who recently chose to stay home, instead of heading to London for a game against the Washington Wizards.
Turkish authorities are also seeking an Interpol Red Notice, to formally request his extradition to Turkey.
