Officials have issued a warning about lithium-ion batteries after one sparked a fire which tore through a family home.

Norfolk County Council has put out advice about the items - which are found in many everyday household devices - in the wake of the blaze in Bowthorpe last Tuesday.

Investigators concluded the fire was triggered by a lithium-ion battery that was being recharged for a small boat which householder Chelsea Robinson's son used for fishing.

The battery and its charger had been purchased online and the council's Trading Standards department is trying to identify the retailer and the exact model involved.

As the investigation continues, officials have urged people to only buy the devices from reputable traders.

Margaret Dewsbury, a senior councillor, said: "You can reduce the risk of fires by checking batteries regularly and ensuring you only buy from reputable retailers so that products meet UK safety standards.

"Look out for warning signs of problems, such as wear and tear, overheating, an unusual smell, unusual sounds or a battery or charger that is bulging out of its usual shape.

"If you see any of these signs, turn it off, unplug it and take it outside if it is safe to do so."

Before the fire broke out last week, Ms Robinson noticed that the battery had started to swell and smoke, before eventually exploding.

Emyr Gough, head of prevention at Norfolk Fire and Rescue Service, said: "Unfortunately, this fire has started with a battery and had devastating consequences for the residents as their home has been significantly damaged."

Lithium-ion batteries can be found in a range of devices, including mobile phones, tablets, laptops and mobility scooters.

They have been linked to several fires and a safety bill relating to their safe storage, use and disposal, is due to be debated in the Houses of Parliament later this week.
