NIAGARA, Wis. — The Marinette County Sheriff’s Office and the Brown-Outagamie Bomb Squad detonated explosive devices in Niagara and the town of Stephenson in Wisconsin this week.

There is no current threat to the public as the potentially dangerous materials were disposed of by professionals, according to a release from Marinette County Sheriff Jerry Sauve.

The first incident occurred on Army Lane in the Town of Stephenson and the second — which involved 90 blasting caps in an outbuilding — on Van Ginkel Road in Niagara, the release stated.

A blasting cap is a device that initiates the detonation of an explosive such as TNT or dynamite.

The MCSO encourages the public to be aware and watchful of any suspicious or potentially dangerous explosive devices while cleaning outbuildings and surrounding property. Older devices and dynamite are known to be unstable and volatile, the release stated.

Anyone who comes across such items should contact Marinette County Dispatch Center at 715-732-7627.
