POLICE closed off part of a road after a loud bang was heard from beneath the street.
Residents dialled 999 after hearing a loud noise in Ladybridge Road, Purbrook, at about 7.15pm on Saturday.
A fire engine from Waterlooville was called out but it was quickly determined that the sound came from an underground electricity cable.
A total of 35 homes were without power for a short time until contractors from Southern Electric reconnected them to a different part of the network.
The road was closed westbound by police, near the junction with London Road, at about 8.15pm.
The closure allowed contractors from Southern Electric to establish what the problem was.
Company officials said there was a fault in one of the cables.
A spokeswoman for Southern Electric said: ‘We got the first report of it where people heard a loud bang in the street.
‘The cable popped so that is where the noise came from.’
The road was reopened by 8.45pm and properties were reconnected to their normal network by 1am yesterday.
A company spokeswoman said contractors would be carrying out further repair work on the cable today.
