In a bombshell development that’s sending shockwaves across the world, a chilling 10-minute video purporting to be CCTV footage from inside the doomed Le Constellation bar in Crans-Montana, Switzerland, has been leaked online – capturing the entire horrifying sequence of the New Year’s Eve fire that turned a vibrant party into a deadly trap.

The grainy but devastating clip, which has rapidly gone viral on social media platforms, shows the packed basement nightclub buzzing with excitement just after 1:30 a.m. on January 1, 2026. Hundreds of young revelers – many teenagers celebrating the new year – are dancing, laughing, and toasting with champagne.

Then, in a moment that has left millions furious and heartbroken, the tragedy unfolds in real time.

What shocked everyone the most? It turns out THIS very action – staff and partygoers hoisting champagne bottles topped with blazing sparklers high above their heads – was the fatal spark that caused the fire to erupt!

The footage allegedly shows a waitress, perched on a colleague’s shoulders in a classic VIP bottle service stunt, waving bottles adorned with fountain sparklers dangerously close to the low ceiling. Sparks fly upward… and suddenly, flames erupt across the acoustic foam insulation!

In seconds, the highly flammable foam ignites like a wildfire, spreading rapidly across the ceiling in a terrifying flashover. Screams replace the thumping music as black smoke billows, engulfing the room. Partygoers frantically rush toward the narrow staircase – the only visible exit – leading to a crushing bottleneck that trapped dozens inside.

One brave man is seen desperately trying to beat out the flames with a jacket, while others film on their phones instead of fleeing immediately. Chaos ensues: people trampling, pushing, collapsing as toxic smoke fills the air and temperatures soar.

The “CCTV” captures it all – from the initial spark to the inferno raging out of control, with silhouettes of trapped victims visible in the glow of flames. The final minutes show emergency lights flickering as responders battle to enter, but for 40 souls – including many teens as young as 14 – it was already too late.

Viewers who have watched the leaked video report being left devastated, furious, and unable to sleep. “I couldn’t finish it… seeing those kids realize they were trapped,” one commenter wrote. “How could they allow sparklers so close to that foam? It’s criminal!”

Swiss authorities have confirmed that sparklers on champagne bottles held too close to the ceiling are the likely cause of the blaze, based on witness statements and preliminary forensics. The highly combustible acoustic foam – installed for soundproofing but allegedly non-compliant with fire standards – accelerated the disaster.

Outrage is mounting over safety lapses: Le Constellation hadn’t been inspected for fire safety since 2019, despite annual requirements. The bar’s French owners are now under criminal investigation for negligent homicide.

In the aftermath, the once-lively resort town is shrouded in grief. Makeshift memorials with flowers, candles, and heartfelt notes line the sealed-off ruins.

Families of the 40 victims – including promising young athletes and students from Switzerland, France, Italy, and beyond – are demanding answers. Survivors describe miraculous escapes, like smashing windows or being pulled out by heroes, but many bear severe burns requiring lifelong treatment.

This leaked footage, while unverified as official CCTV (experts suggest it may be a compilation of security cams and phone videos), has reignited calls for bans on indoor sparklers and stricter nightclub regulations worldwide. Similar tragedies, like the Station fire in Rhode Island or Kiss nightclub in Brazil, echo the preventable horrors.

As Switzerland mourns one of its worst modern disasters, this video serves as a gut-wrenching warning: One reckless moment of “fun” can unleash hell.

WARNING: The footage is extremely disturbing. Viewer discretion is strongly advised.
