Five men killed in an explosion at an industrial unit may have been producing illegal alcohol.
Investigators have found evidence to suggest the unit in Boston, Lincolnshire, was being used as an illegal distillery.
Five men, believed to be eastern European, died after the blast last night, while a sixth survived with 75% burns.
Locals near the site of the explosion and ensuing inferno speculated the unit was used as an illegal vodka distillery.
Lincolnshire Police Superintendent Keith Owen said: "What I can confirm is that we have found chemicals on the premises which tend to indicate either the manufacture or production of alcohol."
