On Wednesday, troopers from the MSP Gaylord Post responded to New Beginnings Thrift Shop in Harbor Springs around 2:15 p.m.
When a worker went through a box of donated tools, they found several items believed to be pipe bombs and called 911.
The MSP Bomb Squad took an X-ray of the devices and found one that contained a fuse and powder. They safely disposed of the devices and searched the business and surrounding around for more explosives.
Nothing else suspicious was found. MSP continues to investigate.
