A spokesman for the energy supplier told the Potters Bar Edition it would prosecute anyone found to tamper with its sub-stations.

He said: “We occasionally find that sub-stations are targets for thieves and vandals, and EDF Energy takes incidents like this very seriously.

“Thieves risk serious injury or death by tampering with our equipment.”

The spokesman added: “We will help police with their inquiries and press for prosecution.”

A police spokeswoman warned potential sub-station thieves to think twice.

“If tampered with these sub-stations can cause life threatening injuries.
