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. Two of the male suspects had been known to the police due to multiple theft convictions.
On the day of the heist, the suspects arrived shortly after the museum opened, using a stolen vehicle-mounted mechanical lift to access a gallery close to the River Seine. They employed a disc cutter to open display cases housing the jewels, leaving with €88 million worth of treasures.
Investigators believe four men executed the theft, with one still at large. Since the incident, security has been tightened across France's cultural institutions, and the Louvre has transferred some of its most valuable jewels to the Bank of France.
