Turkey issued an arrest warrant on Friday for Turkish NBA star Enes Kanter, accusing him of being a member of a "terror group," a pro-government newspaper reported.
A judge issued the arrest warrant after an Istanbul prosecutor opened an investigation into Kanter's alleged "membership of an armed terrorist organization," Sabah daily reported.
Kanter, 25, a centre for Oklahoma City Thunder, previously backed Muslim cleric Fethullah Gulen in Twitter postings after an attempted putsch last July aimed at ousting President Recep Tayyip Erdogan.
Turkey accuses US-based Gulen of ordering the failed coup and refers to the movement as the "Fethullah Terrorist Organization" (FETO). Gulen denies the claims.
The arrest warrant refers to Kanter's alleged use of an encrypted messaging application called Bylock, Sabah said, which Turkey claims was especially created for Gulen supporters.
It also referred to Kanter's "praise for a terror organization" in messages via his social media accounts, the daily reported.
The Swiss-born star hit back at the Sabah story on Twitter, sharing a screenshot of the article, adding: "You cannot catch me. Hahaha. Don't waste your energy.
"I am already going to come to (Turkey) to spit on all of your ugly, hate-filled faces."
Sabah daily added that the prosecutor would apply for an Interpol red notice — to inform Interpol's 190 members that someone's arrest is sought and thus ensure their deportation — to the justice ministry.
Kanter, who has compared Erdogan to Adolf Hitler, was detained in Romania at the weekend after being informed that his Turkish passport had been canceled.
He claimed the cancelation was linked to his criticism of Erdogan's government and told reporters on Monday he would seek American citizenship.
