One of the most wanted men in France, Xavier Dupont de Ligonnès, suspected of killing his wife and four children in Nantes in 2011, was arrested in Glasgow.

58-year-old Dupont de Ligonnès was wanted since 2011, when five members of his family were found buried in their garden in one of the country's most notorious cases and were arrested today at Glasgow Airport.

The managing director Dupont wrote then in a bizarre letter to the family members, he was a secret agent and move with his family as part of a witness protection program of the Secret Service to America.

The family was missing on April 3, 2011 and the bodies of Dupont's wife Agnesa and their children Tomas (21), Arthur (18), Anne (16) and 13-year-old Benoit were later found later this month.

A search was quickly launched for Dupont, who remains the main suspect. Despite numerous alleged sightings in the meantime, including when 50 police and firefighters searched caves in southern France, he has not been seen since.

AFP reported that Dupont was arrested at Glasgow Airport this afternoon after boarding an easyJet flight from Paris Charles de Gaulle.

Le Parisiens newspaper reported that he traveled under a false name but was captured after a positive fingerprint had been identified.

He should not have resisted his arrest.

It is assumed that Dupont, who had a red flag from Interpol, was noticed by the staff of the French airport, but had no time to prevent him from getting in.

He was subsequently arrested by police at Glasgow Airport, reportedly warned of his arrival.
