A woman has had to undergo skin grafts after suffering serious burns to both legs when the toilet she was sitting on exploded underneath her.
Police believed the blast was a result of the unhygienic conditions of the septic tank and lack of ventilation in the toilet cubicle at a bar in Barcelona, The Local reported.
When the woman switched on the light, a spark ignited methane gas which had filled the toilet.
The gas was compressed by the woman sitting down, which caused a stronger blast.
She suffered second and third degree burns to her legs.
The woman has sued the owners of the bar, Catalunya Radio reported.
