Suspected explosive device detonated in Nederland

NEDERLAND, Colo. -- A suspected explosive device discovered near the Nederland Police Department was detonated early Wednesday morning, the Boulder County Sheriff's Office said.

The FBI's preliminary investigation found that it was an active improvised explosive device that failed to detonate.

The device was left sometime during the early-morning hours Tuesday. It was discovered in a backpack just before 8 a.m. Tuesday.

Nederland Town Marshall Paul Carrill said officers initially believed the backpack was lost property. It was brought inside police headquarters and after looking inside the bag, it was determined the building and the Caribou Ridge Shopping Center needed to be evacuated.

The bomb squad moved the device from inside police headquarters to the shopping center parking lot.

After a long investigation, it was determined a controlled detonation by the Boulder County Bomb Squad was needed for the safety of the public. It was conducted about 1:30 a.m.
