FOND DU LAC -- The County Government Center in Fond du Lac was closed off Tuesday night, April 12th after a resident brought in what officials believed to be a World War II era Bazooka rocket.
According to WLUK, Fond du Lac police were not sure if there was any explosive element to the weapon, or if it was a training tool.
Officials treated it like it is explosive -- and later determined the round was not live.
WLUK says the resident found the device while cleaning the basement of an older home.
The area has since reopened.
