The suspects were apprehended at their homes early Tuesday, with 14 taken into custody, one source told AFP. During the operation, police and customs officers seized nearly 10 kilograms of herbal cannabis and cannabis resin, €20,000 ($21,700) in cash, and 48 mobile phones, the source added.

The operation, conducted close to the Olympic village, targeted a known dealing location that police have been monitoring in preparation for the Olympic Games, which begin on 26 July, another police source said. In recent months, police have intensified operations in Seine-Saint-Denis, where the athletes' village is situated.

The Olympic Village, the largest new-build project for the upcoming Games, is located on a riverside site in Seine-Saint-Denis, an area undergoing regeneration in this economically deprived suburb. It will house over 14,000 people in 82 buildings spread across the municipalities of Saint-Denis, Saint-Ouen, and Ile-Saint-Denis, north of Paris.

A Senate committee of enquiry published a report in mid-May warning of the increasing influence of drug trafficking in France, highlighted by a surge in violence linked to competition among criminal gangs. According to the senators, drug trafficking in France generates between €3 billion and €6 billion ($3.2 billion and $6.5 billion) annually.

Paris prosecutor Laure Beccuau stated in early May that she expects a rise in crime during the Olympic Games in Paris. "There will be many more tourists," she told Franceinfo radio.

"This means that the criminals will attack these tourists," she said, pointing to pick-pocketing, housing scams and other crimes.
