The sound of gunfire outside the Mass. Ave. Orange Line station around 3 p.m. brought police racing, led to the road being shut for the investigation between St. Botolph and Columbus and a halt to Orange Line service as police searched the station for possible shooters.
Police are looking for two men seeing fleeing on bicycles towards St. Botolph. Both were black. One was in a gray hoodie and pedaling on a yellow, 18-speed bike with a plastic rain guard over the rear tire. The other was on a less distinctive bike but was dressed all in red.
