Update 5:45 p.m.
Police in Park Rapids said the shutdown of the western side of the city is over.
Roads were closed and buildings placed on lockdown after the discovery of possible explosives, but at around 5 p.m. Park Rapids PD said the area was opening up again.
Staff at Linda's Recycled Goods initially thought someone had left a donation box filled with old dynamite, prompting the evacuation of the area and the lockdown.
Upon further inspection, the Crow Wing County Bomb squad found they were actually road flares "that very closely resembled dynamite."
"There were no injuries reported during the incident," a police spokesman said. "I would like to thank everyone for their understanding and cooperation."
