Last month's jewellery heist at the Louvre museum was carried out by petty criminals rather than organised crime professionals, Paris's prosecutor has said.
This is not quite everyday delinquency... but it is a type of delinquency that we do not generally associate with the upper echelons of organised crime, Laure Beccuau told franceinfo radio.
She said four people arrested and charged so far over the theft that shocked France and the world were clearly local people living in Seine-Saint-Denis, an impoverished area just north of Paris.
Jewels worth €88m (£76m; $102m) were taken from the most-visited museum, in the French capital, on 19 October.
In Sunday's interview to franceinfo radio, Beccuau said the four arrested people - three men and a woman - all live more or less in Seine-Saint-Denis.
She said two of the male suspects had been known to the police, as they each had multiple theft convictions.
On Saturday, a 38-year-old woman was charged with complicity in organised theft and criminal conspiracy with a view to committing a crime.
Separately, a man, aged 37, was charged with theft and criminal conspiracy. The suspects - who have not been publicly named - both denied any involvement.
Investigators believe four men carried out the daylight theft, and one of them is still on the run. Prosecutors disclosed that the suspects arrived at 09:30 local time (07:30 GMT), just after the museum opened to visitors.
They used a stolen vehicle-mounted mechanical lift to gain access to the Galerie d'Apollon. The men used a disc cutter to crack open display cases, stealing jewels in a mere four minutes.
The authorities fear that the stolen jewels have already been smuggled abroad. Following the incident, security measures have been tightened around France's cultural institutions, with the Louvre transferring some of its most precious jewels to the Bank of France.
