Officers recovered about 100 kilos of drugs, described as essentially cannabis with a small quantity of cocaine.[1] Lyon Capitale, citing Le Progrès, likewise described the find as about 100 kilos, mainly cannabis with a small quantity of cocaine.[2] The premises had been under investigation by the brigade des stupéfiants before the seizure.[2] The same boulevard had previously seen large police deployments after several shootings in March and April.[1]
