Multiple people were shot in a Colorado Walmart Wednesday night, Reuters and the Denver Post reported.
Police did not release any information on the victims. It also was not clear if the shooter had been taken into custody, Reuters said.
It happened in Thornton, about 10 miles northeast of Denver.
“We’ve got multiple parties down, we’re still trying to ascertain what their conditions are,” Officer Victor Avila of the Thornton Police Department told Reuters.
Customers in the store had been self-evacuated after the gunfire.
Police warned people in the area to stay away from the shopping center, the Denver Post said.
