A town centre market day drama in Dereham ended today after Army bomb disposal experts discovered that rusty objects found near a bowls green were wartime RAF fire extinguishers.

Dozens of staff were evacuated from their town centre offices in Dereham and told to go home after five canisters - initially possibly thought to be unexploded bombs - were found at St Nicholas Bowls Club at about 12pm.

Two bowls club members made the discovery while they were laying paving slabs.

Police were unable to say what the cylinders were and set up a 200 metre cordon around the site as a precaution.
