UPDATE: A law-enforcement source and a fan say the victim in the attack was One Armed Push-Up Guy, well known outside Boylston Street bars and in the Fenway for doing one-armed pushups for a fee, like this:
Boston Police report that around 2 a.m., a guy standing in the middle of Boylston Street outside Whiskey's, 885 Boylston St., yelled "Fuck Boston and fuck your businesses!" and then turned around and punched a nearby man, who fell unconscious into the street:
Witnesses reported a cab traveling inbound on Boylston Street ran over the victim while he was unconscious in the road and dragged him under the vehicle.
The screaming puncher then ran inbound on Boylston and disappeared down Fairfield Street, police say. He's described as 30 to 32, 5'10" and clad in a dark jacket with a fur-lined hood.
The cab driver told police he did not realize he'd hit somebody and stopped only when bystanders started motioning to him. The victim was taken to Mass. General and is expected to survive, police say.
If you know the guy, contact D-4 detectives at 617-343-5619 or the anonymous tip line by calling 800-494-TIPS or texting TIP to CRIME (27463).
