CCTV shows teen employee shelter shoppers during shooting

This is the moment a teen employee hid shoppers during a shooting on Halloween night.

CCTV footage from inside the Twisted Escape Room in Vancouver Mall in Washington, USA, shows the teen, 16, sat behind a desk before loud shots ring out.

Upon hearing the shots, the teen's immediate reaction was to get up and lock the front doors.

But seconds later, a group of people ran up to the doors seeking refuge.

Without hesitation, the employee ran back to unlock the doors and beckoned two adults and four children into safety.
