Copper thieves cause Hull power surge
Thieves caused a major power surge affecting 200 homes in Hull when they broke into a substation and removed copper cabling.
Homes in the HU7 postcode area suffered power cuts, voltage irregularities and damage to appliances in the surge at 0530 GMT.
Engineers from CE Electric were trying to repair the 11,000KV substation in Sutton.
The power company said it was an "extremely dangerous crime".
The fire service was advising residents to turn their power off at the main supply point.
CE Electrics said once repairs are complete, engineers will carry out inspections at each of the affected households to check it is safe to restore power.
The company said it is dealing with 17 metal theft incidents on average each week in the Yorkshire area.
It has been hit by 187 thefts since the start of the year, including 11 in Humberside.
Paul Norton, head of health and safety, said: "The mindless actions of these thieves and their complete lack of regard for the consequences of their actions only highlights the extreme lengths these thieves are willing to go to.
"As a company that cares a great deal about its customers, we are committed to tackling this extremely dangerous crime and will be working closely with local communities and the police to raise awareness of these dangers."
