The team said in a statement that riders' rooms were searched by officers at the hotel it stayed in in the southwestern city of Pau.
Judicial officials in Pau confirmed “judiciary actions” took place at the team hotel, without further details.
They said the Marseille prosecutor was in charge of the investigation. The Marseille prosecutor’s office did not immediately respond to a request for comments from The Associated Press.
About 25 officers from a special public health unit (OCLAESP) were involved in the search as part of the operation carried out by French authorities, according to police.
"Despite being unaware of the investigation reasons, the team was also requested to provide all training files which were compiled and presented to the officers as requested," the team said.
"We were greeted by several French police officers. We were not given a warrant to read through, but the team complied with all the officers’ requests," technical director Vladimir Miholjevic said.
"The process had impacted our riders recovery and meal planning, and as a professional team the wellbeing of our team is a key priority."
