A Massachusetts man was arrested over the weekend in connection with a brutal beating in which investigators say he used a metal police baton.

Gregory Knowles, 51, of Hingham, is charged with assault with a dangerous weapon, strangulation, battery and witness intimidation, among other things.

According to police, the 34-year-old victim called 911 around 11 p.m. to report the incident of driving aggression on Route 3A near Sohier Street in Cohasset.

“The victim claimed the driver of the Jeep stopped in front of him, got out with an extendable metal baton and began hitting and strangling him in the head and body before fleeing the scene,” Cohasset police said in a statement. “The victim took down a license plate number while the Jeep fled.”

According to police, the victim suffered visible injuries but refused medical treatment at the scene.

Officers arrested Knowles at his home and towed his 2006 Jeep back to Cohasset Police Headquarters. After obtaining a search warrant, the department said they found the extendable metal baton in the Jeep.

Knowles was scheduled to be arraigned in Quincy District Court on Monday, but the judge ordered a diversion under a state law for veterans. His next court date is scheduled for Aug. 12.
