The owner of the Swiss ski bar at the centre of a New Year's Day inferno that claimed 40 lives and left 119 injured spent time in prison for 'fraud, kidnapping and false imprisonment' and was a known pimp, it emerged today.

French national Jacques Moretti, who is in his 60s, faces charges for the inferno at Le Constellation, in Crans–Montana, Switzerland, on New Year's Day.

His venue became a death trap, after sparklers placed inside champagne bottles ignited the basement ceiling.

On Saturday, multiple media outlets in France and Belgium reported that Mr Moretti, who is originally from the Mediterranean island of Corsica, is well known to the French authorities.

In 2005 he was implicated in a kidnap plot in Savoie, the Alpine department of France close to Crans–Montana, and incarcerated.

Le Parisien reports: 'According to our information, Jacques Moretti is no stranger to the French justice system.

'He is known for pimping cases dating back some twenty years, as well as for a kidnapping and confinement case. He was imprisoned in Savoie.'

Quoting its own legal source, RTL, the radio network, reported: 'The Corsican–born man in his sixties was imprisoned in Savoie in 2005, for involvement in cases of pimping, fraud, kidnapping, and false imprisonment.'

There was no initial response to the revelations from lawyers representing Mr Moretti.

He was questioned by Swiss prosecutors on Friday, along with his wife, Jessica Moretti, who is in her 40s.

Both are currently at liberty, as they assist the judicial authorities with their enquiries.

They have indicated that they will open an enquiry into 'arson by negligence' and 'manslaughter by negligence' if 'criminal liability is established'.

In the meantime, the French couple have not been formally charged, and are free to travel.

Swiss attorney general Beatrice Pilloud said: 'Everything suggests that the fire started with incandescent candles placed in champagne bottles, which were brought too close to the ceiling, causing a rapid and widespread conflagration.'

Mr Moretti has claimed his bar 'followed all safety regulations', despite being inspected only 'three times in ten years' by health and safety officials. Article 8 of the local fire prevention code states that inspections must take place 'every year in buildings open to the public or presenting special risks'.
