An elderly couple sheltered underneath an umbrella as glass "exploded" above their heads without warning at an inner city Queenstown mall today.
"It literally just exploded," a bystander told The Herald.
"You've got glass exploding at the busiest food court in town."

There was no warning of the glass pane imploding at O'Connells Shopping Centre, believed to be caused by scorching temperatures in the city.
