BOSTON— Transit Police are hunting a brazen subway sicko accused of exposing himself and masturbating in front of women on MBTA trains, leaving riders shaken and furious.

According to MBTA Transit Police, the alleged pervert struck multiple times in December on both the Red Line and the Green Line. Investigators say the man deliberately positioned himself near female passengers before exposing himself and committing a lewd act while staring directly at his victims.

Authorities stress this was not accidental or fleeting behavior, but intentional and predatory. Police believe the suspect felt confident enough to repeat the acts on different days, raising concerns he could escalate if not identified.

Surveillance images released by Transit Police show the suspect riding trains and moving through stations as if nothing was wrong — a detail that has only intensified outrage among commuters.

This case follows another subway pervert just days earlier — one that Mass Daily News actually helped catch. A reader tip sent to MDN led Transit Police to the arrest of a Red Line masturbator after MDN published surveillance images and pushed the alert, showing how fast these sickos can be identified when the public gets involved.

This new case has reignited anger over safety and quality-of-life issues on the MBTA, with riders saying women are being forced to stay on guard just to get to work.

Transit Police are urging anyone who recognizes the suspect or witnessed similar incidents to contact investigators immediately at 617-222-1050.
