Fire officials are preparing to conduct a joint investigation with police to determine the cause of a major blaze at a business park located along the border between Nottinghamshire and Leicestershire. Crews from across the broader East Midlands attended the incident at the Hathernware Industrial Estate in Sutton Bonington, which broke out on Wednesday morning. Teams from Nottinghamshire Fire and Rescue continue to work at the scene alongside colleagues from Derbyshire and Leicestershire, as the fire destroyed buildings, cars, timber stock, pallets and pressurised tanks, several of which exploded. This generated loud explosion sounds across the area, with a University of Nottingham student comparing one detonation to something resembling a impact against a structure. A Nottinghamshire Fire and Rescue spokesperson stated that a joint inquiry with Nottinghamshire Police will look into how the fire started. This review is expected to take place on Thursday, depending on when crews fully bring the situation under control. Emergency services announced the response is being scaled back, while train services that had been halted are now running again. Local residents are still being advised to keep windows and doors shut and not to be alarmed by any booming noises coming from the site.
