SACO – Police arrested 15 anti-war activists who chained themselves together and attempted to block the entrance to General Dynamics Armament and Technical Products Co. on Tuesday. An additional 20 to 30 demonstrators held signs, chanted, sang and sold baked goods outside the plant, which manufactures some of the deadliest machine guns in the U.S. military’s arsenal.

Two dozen Saco police, bolstered by 20 state troopers, began making arrests late in the morning after the group refused to leave. The activists, who arrived in Saco from locations across the state, said the demonstration was designed to underscore the disparity between military and educational spending in the United States.
