A total of 14 people, including 6 Nigerian men and 8 Japanese and male and 8 female subordinates, were arrested and charged for alleged violation of organized crime penalties law (concealment of crime proceeds). The prefectural police finished the investigation, which lasted about three years, on April 18th, 2017. According to investigation officials, it is an unusual size money laundering operation in Japan. The prefectural police said that approximately 1.7 billion yen was remitted from abroad and that approximately 1.61 billion yen was withdrawn in March 2014 - December 2015 in 40 accounts. The Nigerian who was arrested is 30 to 56 years old, Udeneu Okechuku, an export trader from Suzuka, Mie prefecture. He was indicted as for an organized crime violation. Some of the Japanese are unemployed and dome are company presidents 43 to 72 years old. In response to the instructions of the Nigerian, the Japanese opened accounts and withdrew cash. Udeneu is suspected to have drawn Japanese people to the windows of financial institutions from May 2002 to May 2003 and drew about 300 million yen while knowing that it was criminal earnings as "money for purchasing goods". Udeneu has been silent. A total of 11 cases (about 570 million yen) have been indicted is a series of cases, and some convictions are confirmed. Udeneu and other Japanese got acquainted with secondhand car exports and others, and the Japanese solicited and gathered other supporters. The compensation for the Japanese is 1 to 4% of the received amount. The prefectural police believe Udeneu and the other suspects sent the laundered funds to overseas criminal groups. Funds are sent to overseas criminal groups taking over the e-mails with actual customers such as companies in 12 countries / regions, such as the United States and Spain, deceiving them by impersonating as a customer and requiring Japanese accounts to which money was sent. Mr. Takumi Kanei, a prosecutor of the former Tokyo District Public Prosecutor 's Office and a special investigator in the Tokyo District Public Prosecutor' s Office (Daiichi Bar Association) said Japan has not advanced measures to fight such crime in comparison with the United States, but if the formal and correct documents are in place, the bank will have difficulty finding money laundering. Although strengthening of the check function is required, there is also a balance problem with a decrease in user convenience and an increase in cost, and understanding of society is necessary. In recent years, the international criminal group's prominence has been prominent in narcotics and weapons trading, etc. In addition to overseas remittance, funds may be used for domestic real estate investment and corporate acquisitions.
