A Bridgewater man who has been charged with assaulting and injuring four Boston Police officers during an altercation at Boston City Hall last week is the same person who disrupted a community meeting at the Trotter School on April 1.

Michael Williams, 51, was ordered held in lieu of $25,000 bail last week at his arraignment on charges he segued from screaming slurs at people inside City Hall to shouting at and then biting and punching Boston police officers trying to get him out of the building, the Suffolk County District Attorney’s office reported.

Williams faces two counts of assault and battery on a police officer, assault with intent to maim, trespassing, resisting arrest and disorderly conduct, the DA’s office says. In addition to setting bail, Boston Municipal Court Judge Paul Treseler ordered Williams committed to Bridgewater State Hospital for observation.

The incident came a week after Williams grabbed the microphone at a Dorchester meeting about White Stadium, declared himself a Nazi and unleashed a torrent of complaints about numerous topics that had nothing to do with the White Stadium issue – including harassment by Boston police officers because he supported the destruction of the Twin Towers in 2001. He then threw the microphone to the floor and stormed out.

According to the DA’s office, Williams became combative inside City Hall last Friday morning after discovering that a meeting he planned to attend had been cancelled. According to a police account, “While trying to arrest Williams, an officer placed his right arm on his shoulder to place him in handcuffs. Williams bit the officer’s hand, causing severe damage, including heavy bleeding and parts of the skin and tissue to hang off the hand. Williams then freed his arms and grabbed and punched two officers with a closed fist, then briefly fled. Officers grabbed Williams and brought him to the ground. He continued to resist arrest until other officers arrived. Williams continued to resist officers during the booking process at Area A-1 station.”

Four officers were transported by Boston EMS to Mass General Hospital to be treated for their injuries.
