An "anonymous denunciation" led to the arrest of Xavier Dupont de Ligonnès on Friday night in Glasgow.

Xavier Dupont de Ligonnès, suspected of the murder of his wife and children eight years ago, was arrested Friday at Glasgow Airport from Paris following an "anonymous denunciation", reported AFP a source close to the survey. This "information" came too late for an intervention on French soil, the same source said. The French investigators warned the Scottish police that he was on the plane and "transmitted means of identification", it added. "To be completely certain, we will wait for the comparison DNA," said this source.
