A WARNING has been issued about unsafe hover boards which experts say pose a major safety risk.

The self-balancing scooters have been marked as a popular Christmas gift but already 15,000 have been siezed by Trading Standards officers nationally.

Major safety risks identified include issues with the plug, cabling, charger, battery or cut-off switch

A spokesman said: "Many of the items detained and sent for testing have been found to have noncompliant plugs without fuses, which increases the risk of the device overheating, exploding or catching fire.

"When items like self-balancing scooters start to sell out at well-known retailers, the void is quickly filled by crooks churning out poor quality imitations that can put people in danger. Don’t ‘panic buy’ from the first website you find – do your usual common-sense checks."

Barnsley Trading Standards officers say they are monitoring the situation.
