A woman has been left in critical condition after an unknown male assailant set her on fire in a suspected random attack on a German tram.
The unnamed man, 46, reportedly doused the woman with a flammable liquid before setting it alight on Sunday morning in Gera, eastern Germany.
Police in the state of Thuringia, where Gera is located, say the suspected attacker is believed to be the husband of the victim, also aged 46.
Other passengers on board the tram had reportedly pressed the emergency stop button during the horrific attack, where the suspect made his escape as soon as the doors opened.
‘The perpetrator took this as an opportunity to flee towards Gera’s Langenberg [district],’ a police spokeswoman said.
The driver of the vehicle then reacted with urgency and began spraying the flames that were engulfing the woman with a fire extinguisher, she added.
The victim received medical treatment on the scene before being flown to a hospital by helicopter with life-threatening injuries.
Other passengers and the driver were offered psychological care following the attack which took place at around 10am local time.
