Eastbound Highway 36 in the east metro was closed early Tuesday after suspicious packages were discovered in Oak Park Heights as part of what investigators now believe was likely a hoax, KARE 11 reports.
A passerby discovered the devices off a walking trail at about 4:45 a.m. and called 911. Bomb squad officers were called, and a total of four devices were found. The items were 6 to 8 inches long and wrapped in foil with wires sticking out of them, Oak Park Heights Police Chief Brian Derosier said, KARE reported. The devices were "beeping," WCCO reported.
But the items were not explosive and investigators believe someone put them there to provoke a police response.
No one was in custody and no one was injured, the Star Tribune reported.
The busy eastbound highway had been closed down outside Stillwater in the area of Kruger Lane near Menards and Kohls. Westbound traffic was not affected.
Roads were re-opened roughly two hours later, shortly before 8 a.m., the Pioneer Press reports.
