TWO factories on the outskirts of Durham have been damaged by fire.

The factory units, which are both in Langley Moor, were hit by separate fires just hours apart.

A small factory on Towngate Business Centre was the first to be damaged. Fire crews were called to the scene at 7.20pm on Monday.

The building, which contained an articulated lorry, suffered an estimated 200,000-worth of damage.

The lorry was destroyed, ten per cent of the roof was wrecked and the rest of the unit was damaged by heat and smoke.

Just hours later, a second fire broke out at the Interfloor factory, on nearby Littleburn Industrial Estate.

Firefighters were alerted at around 1.40pm on Tuesday and contained the fire in a silo.

A spokesman for Durham Fire and Rescue Service said the first fire could have been caused by an electrical fault or a fuel leak and the second is being treated as an accident.
