A father and son escaped unhurt after a blaze broke out in the cellar of their home.
The son was awoken when a smoke detector activated shortly after midnight last night at the property in Fell Lane, Keighley.
A tumble drier had caught fire.
Two crews from Keighley fire station attended and four firefighters wearing breathing apparatus brought the blaze under control within minutes.
There was extensive fire and smoke damage to the cellar area.
It is believed the blaze may have started due to an accumulation of fluff in the drier.
Tony Pearson, watch commander at Keighley fire station, said: “Fluff does collect in tumble driers and we do advise people to clean them out and get them serviced from time to time. On this occasion the smoke detector proved its worth and both occupants got out OK.”
