Early this morning a parent noticed a small metal pipe sitting in between two cars in the parking lot of the Hermantown Area Family Resource Center just north of Duluth.
The pipe was about one inch in diameter and six inches long, and it looked like it could've been sitting there for a while, perhaps recently uncovered by melting snow, according to Hermantown Police Chief Jim Crace.
The parent, understandably concerned, called police at 9 a.m. and the building was evacuated. Then the Crow Wing County Bomb Squad and members of the 148th Air National Guard moved in to take a closer look around 1 p.m.
"Clearly it was dangerous. Anything like that is nothing to mess with," said Crace.
The bomb squad performed an initial blast to open the pipe for further examination and dispose of it off-site.
Hermantown police have not uncovered any leads and have handed the case over to the FBI.
"We haven't found [any leads] yet, and probably won't until we get the full analysis of the device and its contents, then I imagine the FBI will start working on that," said Crace.
