A BLAZE tore through an industrial unit last night.

Two crews from Essex Fire and Rescue attended the fire in Gravel Lane, Chigwell, at about 11.13pm last night (Monday, May 7), but requested a back up crew when they saw the extent of the fire, which raged in the back of the unit.

Fire fighters had extinguished the blaze by 12.56am.

The fire service and Essex Police are conducting a joint investigation to establish the cause of the fire.
