A man has been arrested on suspicion of arson following a fire which gutted a snack-making factory. The chief executive of the Northern Ireland company Tayto Group, which owns the south Wales plant, shared concerned for the employees. "Our focus now is on what we can do for those staff, who are naturally concerned for their jobs," said the head of the UK's third largest snack manufacturer. Some 75% of the factory was already ablaze when fire crews arrived.
