Anna Ursu, 18, went to the train station in the northern Romanian town of Iasi in the hope of taking a ‘special’ selfie to post on Facebook.

But she accidentally touched the electrical field of a live wire with her leg while lying on top of the train, sending 27,000 volts through her body and causing her to burst into flames while her friend was sent flying through the air.

A passer-by attempted to save Anna and extinguish her flaming clothes, but the 18-year-old died in hospital with more than 50 percent burns.Her friend, 17, is recovering in hospital.

The passer-by who attempted to save Anna said he knew the dangers and called for the girls to get down when he saw them on top of the train.

They failed to hear him, however, and moments later, he heard a bang – and Anna burst into flames.

A hospital spokesman was reported to have said that coming into contact with an electrical field can be just as dangerous as touching a live wire.
