A former longtime worker at Danbury City Hall has filed a federal lawsuit against the municipality, claiming she was retaliated against after complaining of racial discrimination and hostility.

In her lawsuit, filed Monday in U.S. District Court for the District of Connecticut, 58-year-old Marlene Moore-Callands, who is black, claims her supervisors treated her differently from white colleagues due to her race. She also claims the city knew about the alleged behavior, but did nothing to stop it.

Danbury Corporation Counsel and Chief Legal Officer Robert Yamin declined to comment on the lawsuit. But the city's outside counsel at FordHarrison issued a brief statement Tuesday, saying it could say little on personnel matters.
