The older man wound up being shoved into a bathtub, where Fairbanks then bounced his father’s head off the broken toilet, according to police.
Fairbanks, who at the time of his arrest held a Class A firearms license issued by the town of Newbury, had several weapons in the apartment, including a Colt .45 pistol, a rifle scope and “sniper stand,” as well as a collapsible baton and a Marine-issued Ka-Bar knife.
However, he also had a rifle in his trunk and a .38-caliber handgun in the center console of his car, which led to the charge of improper storage of firearms, police said.
Fairbanks is due back in court Feb. 15.
