ZDNet - An international crackdown on Internet financial scams this year has yielded more than $2.1 billion in seized fake checks and 77 arrests in the Netherlands, Nigeria and Canada, U.S. and other country's authorities said on Wednesday. The scammers, use ploys such as "spam" e-mail offering to pay recipients "processing fees" for depositing checks, which later turn out to be phony, and sending the proceeds to the scammer. The crackdown netted 16 arrests in Nigeria, 60 in the Netherlands and one in Canada, said Greg Campbell, U.S. Postal Inspection Service inspector in charge of global security. Nigeria has brought to court 290 cases of suspected fraud, and the prosecutions have been successful in 115 of the cases so far, said Ibrahim Lamorde, head of that country's Economic and Financial Crimes Commission.
