Two money laundering networks, one African, the other Pakistani, were discovered in 2018 via wiretapping, during an investigation into drug trafficking in Brittany. These two international money laundering networks are sentenced to up to 8 years in prison.

The specialized interregional jurisdiction (Jirs) of Rennes sentenced to sentences generally in line with the requisitions, of the defendants, aged 34 to 58, for money laundering or money laundering in an organized gang. The court issued six arrest warrants against defendants who were absent during the deliberations. Two big collectors, a 44-year-old Mauritanian and a 34-year-old Malian, were sentenced to five years in prison for their involvement. Another 44-year-old Congolese collector was sentenced to three years in prison, including 18 months suspended.

Finally, two other defendants, a 37-year-old Frenchman and a 58-year-old Senegalese were sentenced to one year in prison and an 18-month suspended sentence respectively. In the latter, described as "nurse", the investigators had found nearly 500,000 euros in cash. Via the Pakistani network, investigators estimated that more than 43 million euros were laundered between 2018 and 2020.
