New York Knicks team president Isiah Thomas is accused of sexual harassment and discrimination by one of the team's former front-office employees in a federal lawsuit.

Anucha Browne Sanders claims Thomas made unwanted sexual advances toward her and refused to stop, according to the lawsuit filed Tuesday in federal court in Manhattan. Thomas and Madison Square Garden are listed as the defendants in the lawsuit, which charges them with sex discrimination and retaliation.

According to the lawsuit, the 43-year-old Browne Sanders sought assistance from her supervisor, Steve Mills, the president of Madison Square Garden Sports, but said Mills didn't do anything about the situation.

Browne Sanders, who had been with the team since 2000, claims she was fired as the Knicks' senior vice president of marketing and business operations last week as a result of her complaints.
