The Walmart at 2032 Dell Range Boulevard remains closed after being evacuated this afternoon.

Cheyenne Fire Rescue spokesman Scott Smith says crews were called to the store at 11:42 a.m. for a carbon monoxide issue.

"(They) asked us to evacuate the store at 2 p.m.," said Walmart spokesman Casey Staheli. "We're still waiting for what investigators find and what recommendations they have (before reopening.)"

Staheli says no injuries were reported and no one has come forward complaining of any sickness.

"We do apologize to our customers for any inconvenience this temporary closure may have caused and we encourage them to keep an eye on the store Facebook page for any updates on when the store may reopen," he said.
