A teenage girl has tragically died in Vietnam after being electrocuted in her sleep by her faulty iPhone charging cable.

Police in Hanoi said Le Thị Xoan had reportedly rolled over onto the torn cable and as a result was exposed to the live wire.

The 14-year-old schoolgirl was found unconscious by her parents and rushed to a local hospital.

Doctors were however, unable to revive her and pronounced her dead.

The charging cable is being inspected but the authorities say they are yet to determine whether it was the original Apple wire or a third-party device.
