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.
