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,
BBC reports.
"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.
Beccuau said the two were in a relationship and had children together, without giving any further details.
Two men who had previously been arrested were already charged with theft and criminal conspiracy after officials said they had "partially recognised" their involvement in the heist.
