The Colorado Capitol was closed briefly on Monday afternoon due to gunfire at the nearby Civic Center in Denver.
The shooting took place around 12:30 pm, and a man was wounded, and he was taken to hospital for treatment. His case has not been released.
A suspect, who is also a man, has been arrested by Denver Police.
The shooting appeared to have nothing to do with the Capitol, as the Legislative Council was meeting on Monday, but people were told they could not enter or leave the building as a result.
The Colorado State Patrol said on Twitter that the shutdown began out of “an abundance of caution as the situation evolved.”
House Majority Leader Dania Isgar, D-Pueblo, said lawmakers gathered on the House floor to keep away from the windows as the police responded to the scene. Lawmakers received a fire alert.
The debate in the House of Representatives over a bill requiring people to store their firearms safely has not stopped due to the lockdown.
The closure was lifted around 1 p.m.
This year, lawmakers in Colorado are set to spend more on Capitol security after the building suffered more than $ 1 million in damage during protests over the summer.
