A man in his 40s has been arrested on suspicion of murdering his neighbour after a doorway fire in Walcott.
Emergency crews were called to Coastline Village on Sunday after a reported dispute with a man in his 70s suffering severe burns and later dying in hospital.
Detectives say the pair were neighbours and are probing the events leading up to the blaze. Two properties remain cordoned off and police are appealing for any information.
