MBTA Transit Police on Friday arrested a Marlborough man who is accused of punching two officers and spitting on one, according to Transit Police. Around 7:45 p.m., officers at the Forest Hills station observed John Capehart, 50, holding a hockey stick “in a threatening manner” and yelling at a bus driver, Transit Police said. When officers intervened, Capehart allegedly punched one of them in the chest. Officers took Capehart to Transit Police headquarters for booking, and during the process Capehart allegedly attacked another officer, punching him in the face and spitting at him, Transit Police said. Capehart will be arraigned Tuesday in Roxbury District Court on various assault charges.Todd Feathers can be reached at email@example.com. Follow him on Twitter @ToddFeathers.
