News of a break in the case was first reported by the French news service, Le Parisien  citing anonymous sources,

The newspapers story was confirmed via the Paris prosecutor, Laure Beccuau, who stated that two men in their thirties were arrested.  One subject was taken into custody while preparing to board a flight to Algiers at Paris Charles de Gaulle Airport northeast of the city centre of Paris.  The second suspect was apprehended at a location in Seine-Saint-Denis, a historically working-class immigrant commune in the northern suburbs of Paris.  

Both suspects are said to have prior records according to French media and will likely be formally charged with organised robbery and criminal conspiracy to commit a crime.

In her statement, prosecutor Beccuau expressed regret over the premature press release of information related to the case, emphasising that such leaks could seriously undermine the investigation.  She noted that the disclosure risked hindering the coordinated work of roughly one hundred investigators who have been mobilised to recover both the stolen jewellery and apprehend all those involved in the crime. Her comments reflected concern that publicising sensitive details too soon could compromise ongoing efforts to bring the perpetrators to justice.

The investigation continues as authorities search for the remaining two members of the four-man team as well as the missing jewels.
