The finance company Microsen, founded by the Senegalese financier Moustapha Sow, is at the heart of a vast internal malpractice scandal. According to information reported by Libération, the investigations carried out over the past several months revealed a structured organization within the company itself, involving several of its key employees

As Libération reports, 112 fraudulent transactions were identified by the investigators, for an estimated loss of 208 million CFA francs. The alleged mastermind of this vast operation: a structured network composed of several staff members, each playing a specific role in this fraudulent ballet that took place between January 2022 and March 2025. At the helm, Ousmane Racine Mangane (ex-manager of the Point-E agency), Léon Mamadou Diouf (ex-head of operations), Ndella Mbaye (former cashier), Serigne Cheikh Koki Diop (ex-head of risk and recovery), Amadou Diop Sène (former account manager, now based in Canada), and even some accomplice clients, such as the so-called Y. Diagne

The investigation by the Gendarmerie Research Section (Sr), reported by Libération, depicts a remarkably well-crafted modus operandi: creation of fictional accounts, fraudulent internal transfers, fraudulent internal transfers, branch withdrawals using unsigned slips, then express closure of accounts once the funds have been recovered.

The accounts concerned were sometimes purely fictional, others were said to be “conniving”: authentic customer accounts, but mobilized with their agreement to receive fraudulent funds. For example, Y. Diagne was allegedly contacted by Léon Mamadou Diouf, who told him that his account had been chosen to receive a “grant” from Microsen. He then allegedly asked him to withdraw the funds and give them directly to him.

Legal proceedings are now under way. The main defendants were presented to the prosecutor on Wednesday for criminal association, fraudulent entry and maintenance in a computer system, as well as
