Substation arson sparks St Helens blackout
More than 4,200 homes in Merseyside were left without power after vandals set fire to an electricity substation.
The 33,000 volt substation at the former United Glass Ravenhead site in St Helens was broken into and torched at 1640 GMT on Wednesday.
ScottishPower engineers restored power to 3,000 homes by 1745 GMT and those remaining were reconnected at 1830 GMT.
Fire crews attended and brought the blaze under control and a police investigation is underway.
A ScottishPower spokesman said: "It quite simply beggars belief that anyone would want to take risks with thousands of volts of live electricity.
"The fact that we did not find a dead body at the scene last night is purely down to luck.
"Our engineers were also faced with an extremely dangerous situation, and they worked incredibly hard to bring the power supplies back on as quickly as they did.
"We are working closely with Merseyside Police, but we would also like to ask anyone who may have information on those responsible to get in touch and pass on details."
