PITTSFIELD -- A Pittsfield man is facing charges after struggling with police officers responding to a report of a disturbance at his residence.

Jason Vandeusen, 24, of Bartlett Avenue, was "covered in sweat" and "extremely agitated" when Officers David Kirchner and Michael Murphy arrived at the home at 12:55 a.m. Friday, according to a police report. He was "ranting" about wanting his girlfriend to leave his apartment, and about being in a bar fight earlier that night.

After telling Vandeusen to back away from his "personal space" several times, Kirchner had to "physically push" the defendant away after Vandeusen put his hands on the officer's chest, the report said.

Kirchner then told Vandeusen that if he pushed him again he would place him under arrest. Vandeusen calmed down for a "short time", but became enraged again and tried to push Kirchner from his room, according to the report.

Vandeusen then struggled as both officers tried to handcuff him, but calmed down when the officers informed him he would be Tased if he didn't cooperate.

He was uncooperative when he was booked at the police station, at one point banging his head off the wall of a holding cell, police said. He was taken to Berkshire Medical Center for evaluation.

Vandeusen's mother and sister expressed their concerns for the defendant's mental condition, telling police he takes medication for bipolar disorder that isn't supposed to be mixed with alcohol.

He pleaded not guilty in Central Berkshire District Court on Friday to single counts of assault and battery on a police officer and resisting arrest.

District Court Judge Fredric D. Rutberg released Vandeusen on personal recognizance, and scheduled a pre-trial hearing for Aug. 18.

Attorney Ryan Smith was assigned to represent the defendant.
