DENVER - No devices were found in the State Capitol building following a bomb threat which triggered an evacuation.
The threat was called into a law enforcement agency around 4 p.m.
"Obviously, any threat we take serious. Any threat. And this is one of those that we will take serious," said Trooper Nate Reid with the Colorado State Patrol.
A dog was brought into search the four floors of the capitol where the public has access.
The floors had to be checked multiple times, according to Reid.
"There are magnetometers, if anyone has been to the building, they have to go through a scan before entering the building. We don't believe this threat to be credible at this time," said Reid.
Denver police, firefighters and federal authorities responded to help search the building.
"Those who have not gathered their personal belongings will be allowed to come back into the building once the building is secure," Reid said.
Shortly after 7 p.m. the State Patrol tweeted "No threat found at the Capitol. Business as usual beginning tomorrow morning."
