Disturbing details have emerged about NBA star Kristaps Porzingis' alleged rape of a woman last year.

According to a TMZ report, Porzingis called the 29-year-old black plaintiff "my slave" and "b****" while he raped her in his Manhattan penthouse.

It was reported that the assault took place just hours after the former Knicks forward suffered a knee injury in a game, but the basketball star has since denied all allegations.

Law enforcement sources told The New York Post that the NYPD are investigating the sexual assault claim against Porzingis but could not confirm whether he had used the language reported.

Porzingis' lawyer, Roland G. Riopelle, released a statement on Monday where he said his client went to federal police in December and informed the NBA about the accusations after first receiving the woman's "extortionate demands".

According to the TMZ report, the woman claims that Porzingis arrived at her apartment at 2am on February 7, 2018 before inviting her up to his own apartment where he is accused of sexually assaulting and punching her, saying he "owned" her.

The New York Post reported that the woman had discussed a $US68,000 "hush money" payment with Porzingis, who now plays for the Dallas Mavericks, to pay for her brother's college fees.
