Red Line service is halted at JFK when man jumps on the tracks then runs away

The Red Line and commuter-rail service came to a halt on either side of JFK/UMass shortly after 10 p.m. after a man jumped on the Red Line tracks, ran down them a bit and then jumped off. He didn't start the night as a Red Line track runner but as a simple motorist, except he apparently crashed into a parked car, then ran away and seemed to figure the best escape route might be on the subway tracks.

At last report, Transit, Boston and State Police were all looking for him in the area between the station and Harbor Point.
