LAST UPDATE | 12 Oct 2019

A FRENCH MAN arrested at Glasgow airport is not suspected murderer Xavier Dupont de Ligonnes according to the results of DNA tests, a source close to the investigation has said.

“The test turned out negative,” the source said, in the latest twist in the case since Dupont de Ligonnes disappeared eight years ago following the murder of his wife and four children in western France.

Dupont de Ligonnes is still one of France’s wanted men, eight years after vanishing without trace following the murder of his wife and four children.

Xavier Dupont de Ligonnes was subject to an international arrest warrant for the 2011 killings in a mystery that has transfixed France.

The aristocratic businessman was believed to have stopped at Glasgow airport yesterday after arriving on a flight from Paris, according to two French sources close to the investigation.

The sources confirmed a fingerprint match had been made but one said a DNA analysis was being conducted to be “totally sure” it was him.

It has now emerged that he DNA test was negative. 

The 58-year-old is suspected of shooting his family dead and burying them under the terrace of their elegant townhouse in the western city of Nantes.

Their bodies were found three weeks after the killings, during which time Dupont de Ligonnes reportedly told his teenage children’s school he had been transferred to a job in Australia.

He is said to have told friends he was a US secret agent who was being taken into a witness protection programme.

French prosecutors have said he killed all five of his victims in a “methodical execution”, shooting them each twice in the head at close range with a weapon fitted with a silencer.

He is believed to have covered them in quicklime and wrapped them in sheets before burying them under concrete.

Yesterday, officers had picked out a man at the French capital’s Charles de Gaulle airport, but there was not enough time to seize him, so they alerted British police, who confirmed an arrest had been made.

The man “remains in police custody in connection with a European Arrest Warrant issued by the French Authorities”, a Police Scotland spokeswoman said earlier.

French newspaper Liberation reported that Dupont de Ligonnes had undergone plastic surgery to change his appearance, citing police sources.

For years France has been gripped by the question of how Dupont de Ligonnes had disappeared without trace, with some suggesting he may have killed himself. Hundreds of reported sightings only added to the mystery.

In 2015, a letter and photo of two of his sons, signed with his name and the message “I am still alive”, was delivered to an AFP journalist but experts could not verify its authenticity.

The alleged killer evaded a police dragnet in the Var region of southern France in January last year after witnesses reported seeing a man resembling him near a monastery.
