BOULDER, Colo. -- The FBI said Thursday it was conducting a sweep of the vehicle of a person who claims to have information about the homemade bomb that was planted in Nederland on Tuesday.
The vehicle was parked outside the Boulder County Sheriff's Office. The person came forward to sheriff's officials saying they had information about the improvised explosive device.
The sheriff's office was closed as the sweep was conducted. There were no street closures. The FBI told the Boulder Daily Camera there was no threat to the public.
"They are just being extra cautious," an FBI spokeswoman told the newspaper.
Nothing suspicious was found in the vehicle.
On Tuesday morning, a Nederland police officer found a backpack outside the station and brought it inside, assuming it had been lost or abandoned.
An inspection of the bag revealed an explosive device and the shopping center at 20 Lakeview Drive was evacuated.
The device was determined to be a "legitimate explosive device" that was armed but failed to go off.
The bomb squad detonated it early Wednesday morning.
