Turkey has issued an arrest warrant for Enes Kanter, accusing him of being a member of a "terror group."
A judge issued the arrest warrant after an Istanbul prosecutor opened an investigation into Kanter's alleged "membership of an armed terrorist organisation", Sabah daily reported.
Kanter previously backed Muslim cleric Fethullah Gulen in Twitter postings after an attempted putsch last July aimed at ousting President Recep Tayyip Erdogan.
Kanter has compared Erdogan to Adolf Hitler and was detained in Romania at the weekend after being informed that his Turkish passport had been cancelled
