UPDATE: Graffiti removed.
Transit Police say they are conducting "an active investigation" to find whoever sprayed graffiti on one of the two historic trolleys stored at Boylston on the Green Line.
In the Friends of the Mattapan High Speed Line Facebook group, one person posted photos of the graffiti on car 3295, the more rounded PCC car that is a cousin to the cars still in use on the Mattapan Line. She reports she saw the tagging on her way home tonight.
In 2014, a serial tagger was arrested on charges he wrote his graffiti name on the two cars, then left Boston after he promised a judge he would never do anything like that again.
After becoming a wanted man in both Cheyenne, WY and the San Francisco area for doing something like that again, he returned to the Boston area last year and was arrested after being captured on video scribbling on doors at the Forest Hills T stop.
The graffiti on the trolley today looks different from his typical style.
