The notorious syndicate are suspected of collecting and laundering tens of millions of euros across the country.
It was revealed that 30 Nigerians were arrested during two rounds of judicial police raids in June and September following a 15 month investigation.
Police identified suspects who collected cash from young Nigerian women prostituting themselves in different cities across France, officers said, estimating the network laundered between 30 and 50 million euros $35-58 million) in the last three years.
A hair salon and a grocery store in northern Paris were used as collection points for the money before it was handed over to carriers who concealed the cash in double-bottomed suitcases and left the country.
The carriers would sometimes pass through other European capitals and African countries to avoid suspicion, officers said, but the money was always destined for Nigeria.
