Office Central de Lutte Contre le Crime Organisé (OCLCO)

The Office Central de Lutte Contre le Crime Organisé (OCLCO) is a specialized unit within the French judicial police dedicated to combating organized crime. It plays a crucial role in investigating complex criminal networks and high-profile cases. The OCLCO has recently been in the news due to its involvement in the investigation surrounding the murder of Mehdi Kessaci in Marseille. This case, described as a potential "warning crime," has led to multiple arrests in the Marseille region and the Hérault department. As of late March 2026, several individuals were apprehended and placed in custody, suspected of participating in the murder on the orders of one or more masterminds. The ongoing investigation highlights the OCLCO's active role in dismantling organized criminal activities and bringing perpetrators to justice within France.
