POST FALLS — A small device believed to be a bomb set off a large response Wednesday morning, shutting down Corbin Park and bringing out deputies, firefighters and a bomb disposal unit.

Law enforcement now believes it to be a firework.

“Deputies were able to obtain photographs of the firework from afar and send it to the Spokane Police bomb squad, and the bomb squad confirmed it was a device, responded and rendered it as being safe,” said Kootenai County Sheriff's Office Undersheriff Brett Nelson.  

The device was discovered around 8 a.m. at Corbin Park in Post Falls, leading to the temporary shutdown of park operations. 

Deputies from KCSO and Kootenai County Fire and Rescue responded as more information was collected about the device, which was found on rocks at the beach.

A park employee turned away visitors for more than two hours as the device was analyzed by Spokane Police Department's Explosives Disposal Unit.

The device was determined to be safe at 10 a.m. and emergency personnel began to leave the area.

Nelson said the device is believed to be a type of firework. A photo from KCSO showed much of the firework was obscured by black tape, except for the fuse. 

Visitors were allowed back into the park shortly before 11 a.m. Park staff said they were told by first responders the device was still deemed hazardous.   

Nelson said KCSO believes the firework may be an M-80 and is investigating the device's origins.

    Park staff at Corbin Park said the suspicious device found on the beach by some rocks by a passerby playing disc golf. Kootenai County Sheriff's Office took photographs of the device from afar and Spokane Police's Explosives Disposal Unit was called in to assess the device. It is currently believed to be a firework.
