Transit Police report arresting Tukan Manley, 31, for an incident on an inbound Red Line train heading towards South Station on June 11.
In the incident, videos of which were posted to Facebook, Manley and others accused the man, 66, of upskirting a woman sitting across from him on the train - and then going after her when she called him out on it. As Manley pummeled him, bystanders yelled at one guy apparently trying to break things up to let the beating continue because the guy deserved it.
After the incident, police say officers found the man slouched on a bench at the South Station Red Line stop, wincing in pain, with "a swollen right eye and cuts about his face" from where they say Manley beat and strangled him.
Manley was charged with assault and battery on an elderly person, strangulation and malicious destruction of property, police say, adding additional people captured in the video may face charges as well.
