Emergency services were called just before 7pm on Tuesday, May 23 to reports of the blaze in Firs Road.

Norfolk Constabulary later announced that it was investigating the fire as arson.

Neighbours said they heard "a group of youngsters" at the site, which has been earmarked for sale by Norfolk County Council, moments before the incident.

"There are always people in there," said June Osborne, whose home sits just yards away from the site. 

"One of them shouted fire and then that's when it started.

"The flames were really high - almost climbing the trees - and there were plumes of smoke."

Another neighbour, Hayley Martin, described the scene as "mayhem". 

"There was smoke everywhere," she said.
