NEW CASTLE, Pa. — City police charged two women with prostitution in the city’s second undercover sting. Both women were arrested in the parking lot of Beer For Less near the Cascade Galleria off the Columbus Inner Belt early Tuesday. Police said the women were arrested separately, but both, when approached by a uniformed officer, tried to claim a friend was picking them up. The man in the car, however, was an undercover police officer. One of the women arrested, Kellie Ann Mars, 21, of New Wilmington, was also arrested two weeks ago in a separate undercover string that netted six women charged with prostitution on the city’s south side. In addition to Mars, Laina Winters, 41, of West Washington Street, New Castle, was also charged with prostitution. She was remanded to the Lawrence County Jail after police found there were three arrest warrants for her from Butler County. Police did not say why she was wanted in Butler County.
