DENVER (CBS4)- The all clear was given for the City and County Building in downtown Denver after it was placed on lock down status Wednesday morning due to what authorities are calling a "credible threat." Police are searching for the person who called in the threat about 7:30 a.m. Wednesday.

Everyone who wanted to get inside the building was urged to take shelter in the Webb Building to get out of the cold during the lock down.

"With the information that was given to the Denver security office, we made the decision to shut down based on the circumstances as well as the information that was shared as well as based on the time frame. It was early in the morning to make sure that we could alleviate or mitigate any threats before it was opened," said Denver Deputy Mayor Murphy Robinson.

The public was urged to avoid the area surrounding the City County Building at 14th and Bannock. Those in the building were urged to stay inside their offices until further notice.
