Police respond to active shooter at Colorado supermarket 

Local reports say that six people are believed to have been killed by a shooter at a Colorado grocery store as video captured multiple people lying wounded inside and outside the supermarket. 

While police have not confirmed any deaths, Boulder authorities said in a tweet that the incident unfolded just before 3pm local time at a King Soopers grocery store.

‘ALERT: Active Shooter at the King Soopers on Table Mesa. AVOID THE AREA. PIO is en-route,’ officers from the Boulder Police Department tweeted.

Two police officers were also seen escorting a shirtless man with blood running down his leg out of the grocery store in handcuffs. It has not been confirmed if the man is the suspected gunman.

There are reports of ‘multiple people down’ and ‘multiple shooters inside’ the store.  

One video of the incident from YouTube shows two victims lying on the ground in the parking lot of the store. 

At least one victim is seen lying on the floor inside the store just moments before more gunshots are heard. Local reports say one victim is a police officer.  

Television helicopter video showed law enforcement vehicles and officers massing outside, including SWAT teams, and at least three helicopters on the roof of the store in Boulder, about 25 miles northwest of Denver.

Just before 4.30pm local time, Boulder police tweeted: ‘Please avoid the area of Table Mesa & Broadway! This is still a very active scene. Do NOT broadcast on social media any tactical information you might see. 

‘We will continue to tweet updates as we have them. If you live nearby please stay inside for now.’

Officers had their guns drawn, and some windows at the front of the store were broken. 

Authorities over a loudspeaker said the building was surrounded and that ‘you need to surrender.’ They said to come out with hands up and unarmed.

A man who said he was shopping at the store told KCNC-TV that he heard a loud bang, then heard another, and by the third, everyone was running. 

He said they ran to the back of the store, found the employee area and workers told them how to escape. He said they walked single file, with their arms on the backs of those in front of them.

An ambulance pulled away from the store, apparently carrying the bleeding man brought out of the store in handcuffs.  

After the bleeding man was escorted out of the store, several minutes later, a line of people who appeared to have been shopping at the time were seen being taken to safety.  

Law enforcement SWAT teams from Jefferson County and Boulder were dispatched to the market in the southern part of the city of Boulder. 

A person who answered the telephone at a nearby sandwich shop said he and his employees were locked down in the back of the store and all were safe. 

Someone who answered the phone at nail studio next door said she and her colleagues were safe. Neither had details on what happened at the market across the street. 

Shortly after learning of the incident, Colorado Gov Jared Polis tweeted: ‘Like my fellow Coloradans, I am closely watching unfolding events at King Soopers in Boulder. 

‘My prayers are with our fellow Coloradans in this time of sadness and grief as we learn more about the extent of the tragedy.’

The King Soopers supermarket is a brand of Kroger in the Rocky Mountain area.
