POLICE officers seized boxes of cannabis from a Sheffield flat after firefighters broke in to put out a fire.
Officers removed 125 plants with an estimated value of £55,000.
Neighbours called 999 after smoke started billowing out of the upstairs windows of a flat on Mansfield Road, Intake.
But when fire crews from Central and Mansfield Road stations arrived at the apartment, above a barber’s shop, they were surprised to discover a cannabis factory.
They extinguished the blaze and called the police.
The flat was empty when firefighters arrived.
Onlooker Paul Faulkner said: “There was smoke pouring through the upper windows. The firefighters broke down the door and entered with breathing apparatus.
“There were three fire engines and a high-level platform, which they didn’t use.
“Then later the police arrived and started bringing out boxes of cannabis.”
A South Yorkshire Police spokesman confirmed officers had discovered a cannabis factory at the address and no-one was arrested.
The incident comes just weeks after Sheffield’s top judge Alan Goldsack QC warned that anyone caught growing cannabis plants would go to jail immediately.
Judge Goldsack said a new Court of Appeal ruling meant judges had to get tougher handing down sentences for the cultivation of the Class B drug and jail was inevitable.
