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 noted that the four arrested people - three men and a woman - all live more or less in Seine-Saint-Denis. She mentioned that two of the male suspects had previous police records for theft.
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 37-year-old man was charged with theft and criminal conspiracy.
The suspects, who have not been publicly named, have denied any involvement, with Beccuau mentioning that the couple has children together.
Authorities believe four men executed the daylight theft, and one remains at large. The two men who were previously arrested have made partial admissions regarding their involvement.
On the day of the heist, the suspects arrived at 09:30 local time (07:30 GMT), just after the museum opened to visitors. The thieves used a stolen vehicle-mounted lift to reach the Gallery of Apollo and used a disc cutter to break display cases.
They were inside for only four minutes, escaping on scooters before switching vehicles. Prosecutors are concerned that the stolen items may have already been exported internationally.
Since the incident, security measures around France's cultural institutions have been heightened, with the Louvre transferring some of its most precious items to the Bank of France.
