Children on Denbigh hospital roof before fire claim

Part of a fire-ravaged Grade II-listed former hospital will need to be demolished because of the damage caused, Denbighshire council has said.

The blaze broke out at the former North Wales Hospital, Denbigh, at 03:00 BST on Friday.

About 40 firefighters battled it overnight, with the roof collapsing.

Terry Williams, head of community safety at North Wales fire service, said they were working with the police to investigate rumours children had been seen climbing on the roof before the blaze started.
