Equipment for distilling alcohol has been discovered at the Boston explosion site where five people were killed and another hospitalised.
Rumours suggested that the Broadfield Lane industrial site blast was caused by an illegal vodka distillery as locals told reporters that men of eastern European origin has been brewing vodka in the industrial unit.
Police have confirmed that recent evidence indicates there is truth in these rumours.
Lincolnshire Police Supt 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."
The hospitalised man has been left so disfigured that he has no recognisable features.
