POST FALLS - A bomb squad from Spokane was called upon to detonate two suspicious devices on Wednesday near a pump house at Ford Rock off Third Avenue in Post Falls. The two small homemade devices with fuses wrapped in black duct tape were discovered by a city water department employee during routine work at 10:15 a.m. "We believe they may have been there for up to a week," police Lt. Pat Knight said. "The person who found them said the last time he was there was a week ago." The devices - one appeared to be made with a pipe, the other a can - were on a rock just outside a fence surrounding the pump house. "They appeared to be makeshift, with more than likely gun powder inside," Knight said, adding the bomb squad didn't reveal the exact contents. A bomb squad member, wearing a protective outfit, moved the devices from the site to across Third on vacant property formerly occupied by a trailer park to detonate them. There were no evacuations. "The residences in the area were far enough away that we did not feel the need," police Chief Scot Haug said. Traffic on Third was diverted to alternate routes for about 25 minutes during the operation. The scene was cleared at 1 p.m.
