Swiss authorities said on Tuesday that the bar that burst into flames in an upscale ski resort, killing 40 people at New Year, had not had a mandatory annual inspection since 2019, underlining concerns about what safety measures were in place.

Witnesses said it was one of those bottles — with a sparkler attached — that caught the ceiling of the basement “Le Constellation” bar on fire.

Swiss authorities have put the two people who ran the bar under investigation on suspicion of crimes including homicide by negligence.

The fire that killed at least 40 people in a Swiss bar on New Year’s Day was made more likely by apparent flaws in the site’s design and management, experts say.

All 40 people who died in the fire at the Constellation bar near the Crans-Montana resort in southern Switzerland have been identified and ranged in age from 14 to 39, police in the Swiss canton of Valais said Sunday.
