NORTH ADAMS, Mass. — State and local police are investigating a reported armed home invasion on Washington Avenue.

According to a safety alert sent out by Massachusetts College of Liberal Arts campus police, three men left the scene in a blue Volvo late Tuesday morning.

One was armed with a handgun.

North Adams Lt. Jason Wood said the reported invasion is believed to be an isolated incident and residents do not have to take extraordinary precautions other than being observant of their surroundings.

"It's still unfolding," he said. "That's the best we can do right now."
