"It is safe to return to your homes or places of business if you were evacuated," the department said. "We thank you for your patience and cooperation during this event."
Fort Collins police said the backpack contained chemical substances from a cleaning crew. On Friday afternoon, they identified that substance as pre-mixed ANFO, or ammonium nitrate/fuel oil, an industrial explosive frequently used in mining operations.
"Staff at a commercial storage facility were cleaning a unity & located a backpack containing unknown chemical substances," police said. "The Northern Colorado Bomb Team responded to investigate & safely removed the materials for further processing."
