Amazon has emailed customers telling them to "dispose" of their self-balancing scooters, or ‘hoverboards‘, as concerns mount over the toys’ safety.

The eCommerce giant urged customers to take the product to a recycling point for electronic equipment in an email seen by the Telegraph.

It was not specified whether this applied to all models of the self-balancing scooter.

This is not the first step Amazon has taken to cut sales of the product; last week Amazon began removing the item from its site, including those produced by the popular vendor Swagway.

A search on Amazon’s UK site shows only accessories and accompanying items being sold.

In addition to Amazon, John Lewis and Argos have suspended sales.

Reports of the self-balancing scooter catching fire are widespread.

On 11 October, four fire engines and around 20 firefighters attended a fire at a flat in Southwark which involved one of the items that was charging.

Concerns include safety issues with the plug, cabling, charger, battery and cut-off switch within the board.

Some hoverboards have non-compliant plugs without fuses, according to National Trading Standards.

As of 3 December, Officers from National Trading Standards had examined more than 17,000 ‘hoverboards’ at national entry points, with over 15,000 being assessed as unsafe and detained at the border.

Leon Livermore, chief executive, Chartered Trading Standards Institute (CTSI), said: "Criminals and irresponsible manufacturers will often exploit high demand and attempt to flood the market with cheap and dangerous products.

"Consumers should not let a new fashion or craze cloud their judgement and remain vigilant at all times, to avoid taking home an unsafe product."

Livermore called on retailers to take responsibility for problems with the products:

"Trading standards services take product safety extremely seriously but retailers must share this responsibility, to stop substandard products entering the marketplace."
