BOULDER, Colo. (KDVR) — Police say suspicious items found near the Pearl Street Mall in Boulder have been checked and are not a threat. An earlier mandatory shelter-in-place order has been lifted. At the time, police told people to evacuate the area.

The area was closed for nearly four hours. Police say that “out of an abundance of caution” dogs trained in bomb detection checked the area before it was reopened to the public.

Police had initially tweeted that there was a bomb threat. Shortly after, they clarified the situation on Twitter.

“We have NOT confirmed the bomb threat on the Pearl Street Mall but are asking people to take these precautions while we check out the area and investigate. As soon as we have additional information to release we will update everyone,” shared BPD on Twitter.

Colorado State Patrol, Boulder Fire Department, and the Boulder County Sheriff assisted in this investigation.
