LEONIA - Police say a worker renovating a home in Bergen County found a Civil War-era cannonball inside the home.
Leonia police were called to the Leonia Avenue home Tuesday after the worker discovered it on a basement windowsill.
Capt. Scott Tamagny tells News 12 New Jersey that most cannonballs are made up of solid metal, but this one had a cap on it, leading the officers to fear it may have had some explosive material inside.
The Bergen County Sheriff's Bomb Squad was called to remove the cannonball and safely dispose of it.
Capt. Tamagny says the home's previous owner was a history buff.
The captain also says that any citizen who may come across old wartime items should call police if they fear the items are dangerous.
