The BBC has spoken to six women in the US who say they have been tracked using Apple AirTags.

The button-sized devices are designed to work with Apple’s ‘Find My’ network to locate lost items. But there have been multiple reports in the US of the devices being used to track people.

Apple told the BBC: “We take customer safety very seriously and are committed to AirTag’s privacy and security.”

The company also says AirTags have better security features than rival products. However, there is growing evidence that they are being used for criminal activity across the US.
