French police have arrested 15 people for drug trafficking near the athletes' village built for the upcoming Olympic Games north of Paris, police sources said on Wednesday, May 29.

They arrested the suspects at their homes early on Tuesday and took 14 of them into custody, one of the sources told Agence France-Presse (AFP). Police and customs officers seized just under 10 kilos of herbal cannabis and cannabis resin, €20,000 ($21,700) in cash and 48 mobile phones, the source said.

Paris prosecutor Laure Beccuau said in early May that she expected a spike in crimes 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.

The operation close to the Olympic village targeted a dealing point that police have been monitoring in the run-up to the Olympic Games, which begin on July 26, said another police source.

Over the past months police have stepped up operations in Seine-Saint-Denis, where the athletes' village is located. More than 14,000 people will be living in the Olympic Village, comprising 82 buildings in the municipalities of Saint-Denis, Saint-Ouen and Ile-Saint-Denis, north of Paris.

The village is the single biggest new-build Olympics project, located on a site by the river Seine that is a focus for regeneration efforts in the economically deprived suburb of Seine-Saint-Denis.

In a report published in mid-May, a Sénat committee of enquiry warned of the growing influence of drug trafficking in France, marked in particular by an upsurge in violence linked to competition between criminal gangs. According to the senators, drug trafficking in France generates between €3 and €6 billion euros ($3.2 billion and $6.5 billion) annually.
