A fireworks company that held displays in Winchester had its license suspended from the state Fire Marshal's Office after unexploded fireworks shells were left in Waltham.
A city worker mowing a lawn in Waltham ran over an unexploded shell on July 9, causing it to explode, according to the Globe. The lawnmower protected the roker from injury.
On Tuesday, July 10, an undetonated firework exploded in Stoughton when a landscaper went over it with a lawnmower when cutting the grass in the outfield of the Stoughton High baseball field. There were no injuries.
A second undetonated firework was found during a precautionary sweep of the field the following day by Stoughton officials. This firework was detonated by the Massachusetts State Police Bomb Squad.
Unexploded fireworks shells were also found in Ware and Worchester.
The Fire Marshal's Office has also ordered the company to return to the impacted towns and search for any additional shells, according to the Globe.
