Swiss prosecutors summon owners of ski resort bar after deadly blaze

Swiss prosecutors summoned on Friday the two owners of a ski resort bar where a fire on New Year's Day killed 40 people and a local newspaper said one of the couple had been detained, as calls grow for those responsible to be held to account.

Prosecutors are investigating the French owners on suspicion of crimes including homicide by negligence, while victims' families have filed legal complaints over the fire at the 'Le Constellation' bar in Crans-Montana in the Canton of Valais.

One of the couple, Jacques Moretti, has been remanded in custody due to a potential flight risk, Swiss newspaper 24 Heures reported, citing unidentified sources.

The Valais police declined to comment, referring questions to the prosecutor's office, which did not immediately respond to a request for comment.

Earlier on Friday, Jacques and Jessica Moretti did not respond to reporters' questions as they entered the prosecutors' office in the town of Sion. Swiss authorities have designated Friday a national day of mourning.

The couple have expressed their grief over the fire and said they would cooperate fully with the investigation. More than half of those who died were teenagers and a further 116 people were injured, many of them seriously.

Several French and Italian citizens were among the dead, and Italy's Prime Minister Giorgia Meloni called for stern punishment to be meted out to those responsible for the blaze.

Italian President Sergio Mattarella and French President Emmanuel Macron joined Swiss leaders, victims' families and firefighters at a ceremony on Friday in the town of Martigny, where a minute's silence was held to remember the victims.

Dozens of people also stood near the shuttered bar in nearby Crans-Montana in silence, heads bowed under heavy snowfall.

Authorities placed hundreds of letters, teddy bears and bouquets of flowers for the fire victims beneath an igloo to protect them from snowfall.

POLITICIANS CALL FOR FULL ACCOUNTABILITY

Speaking at the Martigny ceremony, Swiss President Guy Parmelin said he hoped that those responsible for the fire would be brought to account "without delay or leniency".

That must also include relevant political authorities, said Mathias Reynard, head of the Valais government.

Speaking in Rome on Friday, Meloni pledged to help the families of the Italian victims find justice, and said she was weighing a ban in Italy on the use of sparklers indoors.

"What happened in Crans-Montana is the result of too many people not doing their job or thinking they were making easy money. Those responsible must be identified and prosecuted."

Witnesses and prosecutors have said the blaze appeared to have been started by the use of sparkling candles that set foam soundproofing on the basement ceiling alight.

Questions remain about oversight at the bar, which the local mayor admitted this week had missed multiple safety checks.

Prosecutors said last weekend that the legal criteria to detain the bar's owners had so far not been met.

In a January 6 statement, the owners said: "We are devastated and overcome with grief, our thoughts are constantly with the victims, their loved ones who have been bereaved so brutally and prematurely, and all those who are fighting for their lives."
