Transit police say they arrested a man and a woman at the Uphams Corner MBTA station last Monday night (March 12) who were engaged in sexual activity on a walkway to the northbound platform.

Dorchester residents Alfred Roach, 55, and Iyoki Ortiz, 34, were both booked for “lewd, wanton and lascivious behavior.”

Ortiz, who police say provided “a false name several times,” was wanted on various warrants issued out of Brookline District Court.
