Police arrested a man on the MBTA's Red Line who was accused of threatening to blow up a train with a bomb.
A passenger on the train used a cellphone to report the threat to MBTA police, who arrested Troy Norman, 18, at Wollaston Station at about 10 a.m., Lieutenant Commander Joseph O'Connor said.
The special operations unit for the Massachusetts Bay Transportation Authority searched the train but did not find any weapons or explosives, O'Connor said. Service resumed in a half hour.
O'Connor praised the T's "See Something, Say Something" program that encourages passengers to report suspicious activity in the transit system to authorities.
Norman, of Quincy, was taken to MBTA police headquarters and booked on a charge of making threats, O'Connor said.
