The mine — located in an industrial unit on the outskirts of the English city of Birmingham — was stealing thousands of pounds worth of electricity from the mains supply, West Midlands Police said Thursday.

Police searched the unit in Sandwell on May 18 on the back of intelligence that led them to believe it was being used as a cannabis farm.

Many people were visiting the unit at various points of the day, police said, adding there were numerous wiring and ventilation ducts visible. A police drone also detected a lot of heat coming from the building.

These are all "classic signs" of a cannabis farm, police said. However, officers found a bank of around 100 computers and zero cannabis on entering the building.

"It's certainly not what we were expecting," Jennifer Griffin, Sandwell police sergeant, said in a statement. "It had all the hallmarks of a cannabis cultivation set-up and I believe it's only the second such crypto mine we've encountered in the West Midlands."

Bitcoin miners use purpose-built computers to solve complex mathematical equations that effectively enable a bitcoin transaction to go through. The miners are rewarded for their efforts in the digital currency.
