WESTMINSTER, Colo. (AP) – Authorities found potential ingredients for a pipe bomb in an apartment in suburban Denver, but no explosive devices were found Friday, police said.
A man who has a criminal history involving explosives has been detained for questioning, police said.
The investigation began after a woman told officials at her child’s school that she was concerned about items the man had left in the apartment. Investigators also learned the man had made some mention of bombs, police spokesman Trevor Materasso said.
The man was found driving a vehicle not far from the apartment. Authorities evacuated at least six buildings and a business while checking the home and a bag from the vehicle for explosive devices. Evacuations were lifted after no bombs were found.
Materasso said pipes were found in the apartment, which aren’t illegal on their own. However, given the man’s criminal history, investigators were trying to determine whether they were intended for a bomb.
“We feel we need to look at this a little bit deeper because of that history,” Materasso said.
Meanwhile, Denver police said a suspicious package discovered Friday near Colorado’s main judicial building was inspected and found to be harmless.
The building, which includes the state Supreme Court, was locked down for about an hour, and a busy street was closed while the package was inspected.
