Hucknall sub-station explosion prompts evacuation
Police and fire crews are investigating an explosion and fire at a Nottingham sub-station which forced 12 homes to be evacuated because of smoke.
Firefighters went to the junction of Station Road and Bolsover Street in Hucknall, just after 2000 GMT.
Other nearby residents were asked to keep doors and windows closed and hundreds of properties were left without power overnight.
Nottinghamshire Police said there were no reports of any injuries.
Investigators said the cause of the explosion was still unclear.
Kevin Kennard, who lives in Station Road, said: "We were sat watching the TV, the kids were playing and all of a sudden there was an almighty explosion, a flash and the lights went off.
"We came out and the sub-station was on fire and the explosion had ripped the side out of it."
Transport services were affected for a time with trams terminating at Moor Bridge.
Residents who had to leave their homes were allowed to return before midnight.
Several roads were cordoned off but had all reopened by Thursday afternoon, police said.
