U.S. prosecutors have charged a Lithuanian man with engaging in an email fraud scheme in which he bilked two U.S.-based companies out of more than $100 million by posing as an Asian hardware vendor. Evaldas Rimasauskas was arrested late last week by Lithuanian authorities.

Rimasauskas does not yet have legal counsel, a spokesman for the prosecutors said. The alleged scheme is an example of a growing type of fraud called "business email compromise," in which fraudsters ask for money using emails targeted at companies that work with foreign suppliers or regularly make wire transfers.
