A fire badly damaged a Keighley factory in the early hours of this morning.

The blaze - at Robin Fuels, at the junction of East Avenue and Lawkholme Lane - broke out at about midnight.

Geoff Douthwaite, an employee at the firm, said it would take months for the company to become operational again.

He said he and his colleagues did not yet know how the fire had started.

A spokesman for Keighley Fire Station said four appliances were called to the incident. These included vehicles from Bingley and Silsden, as well as Keighley. Also, a turntable ladder was drafted in from Bradford.

One appliance was still at the scene at about 9am as firefighters continued to dampen down and investigate the cause of the blaze.

The factory is in a one-storey brick building known as Middleton Works.

The plant has been manufacturing and selling environmentally friendly biodiesel since 2007.
