Sickening.
Shaun Dykes, 17, died after he fell from the site on the roof of the Westfield shopping centre in Derby on Saturday afternoon.
The teenager, a student at Heanor Gate Science College, climbed over a railing on the top level of the shopping centre's car park at 2.30pm on Saturday.
A group of onlookers gathered to watch while trained negotiators spent three hours trying to coax him down.
Witnesses said the mob taunted Shaun, who lived in the Derbyshire village of Kilburn, and shouted: "Go on then, jump."
