A Black in-house attorney at the New York Metropolitan Transportation Authority Bridges and Tunnels sued her employer Tuesday, alleging that she was assaulted by a white male supervisor and retaliated against after reporting it.

Kellie Walker, who has worked at the TBTA since 2018 handling employment issues, filed her lawsuit in the U.S. District Court for the Southern District of New York against her supervisor, Victor Muallem, labor relations vice president Sharon Gallo-Kotcher, TBTA and the Metropolitan Transportation Authority. Her claims include discrimination and harassment, retaliation, an equal protection violation of the 14th amendment, and discrimination.
