Residents living near Rathbones bakery on the Durranhill Industrial estate in Carlisle were warned to stay indoors because of thick smoke.

More than 14 fire crews were called out on Saturday to tackle the blaze and it took them all night to control it.

Fire Brigade Watch manager, Cliff Harding, said the cause of the fire is as yet unknown.

Around 200 people work at the bakery and investigators are assessing the damage.
