Old piece of artillery found, detonated at New Jersey school

Police say they’ve detonated an old explosive device found several hundred yards away from a New Jersey school that’s built on the site of a former military base.

Mantua Police Chief Rodney Sawyer tells NJ.com a crew was clearing grounds in a wooded area on the property of Gloucester County Christian School in Mantua Township late Thursday afternoon when they discovered a piece of artillery.

Sawyer says students in after-school and sports programs were evacuated. A team from Joint Base McGuire-Dix-Lakehurst performed a controlled detonation of the explosive. No one was hurt.

Police say classes on Friday were cancelled so authorities could look from more explosives.
