BOSTON — Police offered Keith Ducey a courtesy ride home Wednesday night. He was, by their own description, "extremely intoxicated." He declined. Then he kicked an EMT in the ribs.

According to the police report, Ducey was no stranger to the bar. The bartender, who goes by Kera, told officers he "comes into the bar, orders drinks, and after a couple drinks he starts bothering the customers and being belligerent often."

Wednesday followed the pattern. After being told to behave, Ducey allegedly told Kera: "I'll just slap you," "I'm going to knock you," and "I'm going to punch you in the face." He then pulled out his phone and began recording her inches from her face.

She told him to get out.

A security guard intervened and barred Ducey for a month. Ducey's response, according to the report, was to call the guard the N-word and grab his butt — twice.

Ducey then dialed 911 himself, claiming bar staff had assaulted him.

Officers arrived and quickly determined that was not what happened. They offered Ducey a ride home. He refused. EMS was called. By the time paramedics arrived, Ducey had deteriorated to the point where he was involuntarily loaded into an ambulance — and allegedly kicked the EMT "a couple of times in his right rib cage, while violently resisting."

He now faces charges of assault and battery on a public employee and assault and battery.
