Police Responds To "Active Shooter" At Grocery Store In US' Colorado

Live-streamed video showed at least one person -- a middle-aged man, shirtless and wearing shorts -- being detained by police and led away from the store.

Police responded to an active shooter at a grocery store in the western US state of Colorado on Monday, law enforcement in the city of Boulder said. A law enforcement source told ABC News police had responded to a report of a person shot in the parking area of King Soopers and were subsequently fired at, but did not confirm early reports of multiple injuries. "Active Shooter at the King Soopers on Table Mesa. AVOID THE AREA," the Boulder police department posted on Twitter.
