WASHINGTON, D.C.: A Singaporean man was sentenced to 40 months in prison Thursday (Friday in Manila) for helping ship US-made radio frequency modules to Iran that were eventually found in IED bombs in Iraq. Lim Yong Nam, 43, also known as Steven Lim, pleaded guilty last December in Washington to fraud charges related to US sanctions violations by helping route 6,000 of the modules through Singapore to Iran. Lim and others he worked with had declared Singapore as the final destination for the electronics, but instead they were forwarded from the southeast Asian city-state in five lots to Iran, the US Justice Department said. “Lim and his co-conspirators were directly aware of the restrictions on sending US-origin goods to Iran,” the department said. The modules can be used in networking home and office computer equipment. But in 2008-2009, coalition forces in Iraq discovered modules from the same shipments being used in the detonation systems of unexploded IEDs, or improvised explosive devices.
