An inquest into the deaths of five men, who were killed in an explosion at an illegal vodka factory, has heard it was probably started by one of them lighting a cigarette.
The Lithuanian men died from the effects of smoke inhalation in the blast at an industrial estate in Boston, Lincolnshire, last July.
