A 66-year-old man from Roslindale was arrested Thursday by transit police after he allegedly performed a lewd act inside an MBTA station bathroom, authorities said.
Transit police said a man approached an officer at Back Bay station around 2:30 p.m. and reported that, while inside the men’s bathroom, a man approached him, exposed his genitals, and began to commit a lewd act.
Officers later identified and arrested Neville Pinnock, who was charged with open and gross lewdness.
Police said he is expected to be arraigned Monday in Boston Municipal Court.
Attorney information for Pinnock was not immediately available.
