Transit Police report that a fight that started on an inbound Blue Line train involving several teenagers ended with one firing at least two shots at the Aquarium station shortly before 9:50 p.m.
Police say nobody was hit by the shots, after which numerous people involved in the incident ran upstairs and tried to scatter. Several, however, were quickly nabbed by arriving Transit and Boston Police officers.
Transit Police initially ordered the entire Blue Line shut down to allow for a search of trains for any possible suspects. When service resumed, trains bypassed Aquarium as the investigation continued
