A man has suffered life-changing burns after an explosion at a suspected cannabis farm in Chesterfield.
Derbyshire Police said officers were called to reports of the blast in Summerfield Road, Boythorpe, at about 14:50 GMT on Friday.
The force said a 32-year-old man was taken to hospital.
Detectives said the explosion caused extensive damage inside the detached house and further damage to a nearby property.
A joint investigation between the police and Derbyshire Fire & Rescue Service has been launched into the incident and the scene remains cordoned off on Saturday.
People inside two homes either side of the property were evacuated as a precaution, but were not injured and have since been allowed to return to their properties, officers added.
A spokesperson from the force said: “Residents living nearby may have heard a loud bang yesterday afternoon but we would like to reassure members of the public that there is no wider threat or danger to the public.”
