The shouting match ended when the man chucked the bags on the floor and jumped over the balcony, smashing into Christmas decorations on his way down before hitting the floor seven stories below causing shocked shoppers to flee in panic.
Emergency services arrived at the scene but Tao was killed immediately from the impact of the fall.
A shopping spokesman said: 'His body was removed fairly quickly.

'This is a tragic incident, but this time of year can be very stressful for many people.'
