A woman suffered serious burns to her legs after a public toilet exploded.

The alleged incident was apparently caused by a build-up of methane gas in the lavatory at a bar in Barcelona, Spanish police are quoted as saying.

The fumes are said to have been ignited when the woman flicked on the light switch, causing a spark.

She was reportedly sitting on the loo at the time and later received skin grafts after suffering second and third degree burns.


Methane gas had apparently built up in the toilet because of poor ventilation and hygiene.

The victim has since taken the bar to court over the incident, Catalunya Radio reports.
