Video shows a curtain catching fire as guests waved glowing candles during the circus act, with a server promptly using an extinguisher to douse the flames.

A fire broke out at the Fanatico restaurant on Castellana in Madrid during a cirque-themed dining event, sparked by sparklers used in the performance, and was controlled within about eight seconds by staff with extinguishers.

Spanish media footage confirms guests lit with candles as part of the show, and a server quickly extinguished the fire; there were no casualties in Madrid.

The Madrid incident has renewed safety concerns and drew cross-border media attention, linking it to the Swiss disaster.

In Switzerland, authorities are pursuing legal action over the Crans-MMontana fire, with homicide and negligence charges against the French bar owners; one owner is detained, the other under restrictive measures.

Early inquiries into the Crans-Montana fire cite negligence and the use of acoustic foam in a basement as contributing factors, with the French bar owners facing homicide by negligence and arson-related investigations.

An investigation has been opened for negligence-related homicide, bodily harm, and arson against the French couple who own the Madrid bar; the man is in provisional detention for three months, while the wife remains free but under restrictive measures.

The Madrid incident occurred less than two weeks after the deadly Crans-Montana fire in Switzerland, which killed 40 people and injured 116, reportedly linked to candle sparks and acoustic ceiling foam.

The Crans-Montana tragedy involved a fire at a bar caused by fountain candles, resulting in 40 deaths and 116 injuries.

The Madrid episode followed the Crans-Montana disaster closely, with reports describing candle sparks interacting with acoustic foam as a contributing factor in Switzerland.

GLH Singular Restaurants announced a permanent ban on fumigants and any pyrotechnic elements, as well as smoke effects, across all its venues to improve safety.

The Madrid fire was detected and contained within about eight seconds using extinguishers, with no injuries or structural damage reported.
