THOUSANDS of properties in Colchester lost electricity on Tuesday night following a power cut.

UK Power Networks has now explained what caused the massive outage, which affected "several thousand" properties in more than 22 postcode areas.

The firm says the power cut was caused by a fault on an underground electricity cable.

It affected properties from in the town centre out towards the Greenstead estate from around 7.40pm.

Engineers were rushed to the scene and managed to get power back on for some customers from 8.20pm, however, electricity was restored in stages.
