"I look out my front window, there was a man just completely naked outside my front door,” a Braintree resident said.

Surveillance photos released by Braintree police appear to show the suspect clad in a tightly drawn gray hoodie, gray sweatpants, and white sneakers flashing a gun and stuffing a wad of cash into a backpack.

An Eastern Bank employee said robbery took place at gunpoint. The lockout at the high school has since been lifted.
