Dozens of police officers in Boulder, Colo., were responding to reports of a shooting at a grocery store on Monday.
In a live video stream from a witness at the scene gunshots could be heard coming from inside the store, with officers gathering at the entrance.
Over a loudspeaker, police officers called to the scene could be heard saying, “The entire building is surrounded, you need to surrender.”
“Come out with your hands up,” the officers said.
Using a lift, several officers reached the roof of the building while more than a dozen lined up outside the main doors.
The Boulder Police Department could not immediately be reached for comment.
