A supermarket chain has withdrawn toy dolls from 700 of its stores after concerns one may have started a fire at a branch in north Wales this week.

Kwik Save said the recall of the battery-operated Baby Sounds doll followed a blaze, which badly damaged a store in Colwyn Bay.

The shop will remain closed for refurbishment.

An estimated 4,000 Baby Sounds dolls have been sold since the end of September.

Customers who bought the dolls are asked to return them and they will receive an immediate refund.

Kwik Save is now looking into the possibility that the doll, which gurgles when its chest is pressed, may have caused the fire.

'Possible fault'

The chain is selling the dolls as a Christmas line and Kwik Save said they had undergone strict safety testing.

The £9.99 dolls are described as being 15-inches high and have a bar code reading 5000 1922 13030.

A Kwik Save spokesman said: "The product has been withdrawn from sale owing to a possible fault, which may be a fire risk.

"We have taken the decision to remove these products as a precautionary measure pending a thorough investigation."

The company stressed the doll was just one possible reason for the fire because it was near the seat of the blaze and contained batteries.
