CHICAGO A Nigerian-led crime ring scammed blood donor lists for personal information which they used to create counterfeit credit cards that funded a two million-dollar shopping spree, AFP quoted federal authorities as saying on Friday. The gang stole the identities of more than 2,300 people between May 2000 and May 2001, some of them from a donor list from life source blood services, a Chicago-based blood donor agency. At other times gang members got the personal information by buying people's credit reports off the Internet or scouring the web for personal information, the U.S. secret service said. Two of the gang were nabbed in Chicago, after flying in to appear on a credit card charge in Dupage County. Adekunle Balogun, 30, and Michael Beaudin, 32, allegedly rented their hotel rooms and a Jeep Cherokee with counterfeit credit cards, authorities said. The indictments returned Tuesday by a Grand Jury charge four Nigerians -- Balogun, Beaudin, Mumuni Apooyin, 37, and Abiodun Olorunfemi, 32 -- with credit card fraud and conspiracy to traffic in and use fraudulent credit cards. The charges carry a maximum of ten and five years' jail time respectively. Three U.S. women were also charged in the affair. "This was a well-organized, well-orchestrated group," said Arnette Heintze, special agent in charge of the U.S. secret service in Chicago. "They struck very fast once they got the information." Many of the large-scale identity thefts in the U.S. are connected with organized crime groups from West Africa, in particular Nigeria, Heintze said.
