'We were in Aldi... we heard the word bomb'
Police say around 1,200 homes are being evacuated, after an unexploded World War Two device was found at a building site on Wednesday.
Josh Roberts was shopping in Aldi with his mum when he found out about the ordnance.
He said: "The police officer came quite frantically into the shop really, asking to see the manager.
"We'll leave for however long it needs to take, for everyone's safety at the end of the day."
