Contractors in Waltham, Massachusetts uncovered cannonballs during a dig late Monday morning, prompting a response from the police bomb squad and the fire department.
The Waltham Fire Department notified the State Police Bomb Squad around 11 a.m. Wednesday that a construction worker had uncovered what appeared to be an "unexploded military ordinance" while excavating a trench at a job site.
ATF personnel and a state Hazmat team responded over concerns of environmental hazards, though none were ultimately detected.
