A 40-year-old Bridgewater man remains in custody following an arrest yesterday at his York Street home. Police chief John Collyer confirms a search of the man's home found a large number of weapons including eight long guns ranging from shotguns to rifles including an assault-style weapon. Collyer also says they found marijuana and cocaine inside the home and have dismantled a grow-op. The Bridgewater Elementary School and the nearby high school were locked down for more than an hour yesterday because the man's home is located just a few blocks away. The man has not been formally charged but police expect him to appear in court later this afternoon.
