Police say a man stabbed two people at the Wonderland Blue Line station around 9:30 p.m., then hopped on a Blue Line train. He only got as far as the next stop - Revere Beach - because police had the train stopped there until they could arrive to arrest him.
Transit Police report he stabbed a man and a woman. Both were taken to Mass. General - the man with life-threatening injuries and the woman with less serious wounds.
Preliminary investigation suggests a 49 year old male and his 33 year old female companion had no prior familiarity with a 28 year old male prior to the incident. What precipitated the altercation remains under investigation. However at some point a verbal exchange occurred amongst the trio as they were inside Wonderland Station.
