TRADING standards are warning Back to the Future fans the must-have Christmas toys made famous by Michael J Fox in the hit sci-fi trilogy, the hoverboards, could burst into flames or even explode.

Around 15,000 unsafe hoverboards have been seized at ports and airports around the UK over the last seven weeks, Torfaen council said.

The levitating skateboards were in danger of overheating, exploding or catching fire, and many had plugs without fuses, faulty cables or chargers that could burst into flames.

A council spokesman said that batteries were likely to fail resulting in high energy ignition and rapidly developing fire.

All purchases should be researched before buying, the spokesman added.

Trading standards have provided a link from the Electrical Safety First website which gives sound advice and information on checking the safety of chargers.

Anyone who finds suspect products for sale is urged to contact the trading standards team on 01495 762 200 or the Citizens Advice helpline on 03454 04 05 06.
