An Argentinian whistle-blower claims in a newly filed lawsuit in federal court in Miami that he was brutally beaten and his family’s lives threatened after he exposed alleged bribes paid by German-based Siemens AG to high-ranking government officials — including former president Carlos Menem — to secure a $1 billion identity card contract.

The complaint filed Sept. 12 states Carlos A. Moran, a lifelong government bureaucrat, was assaulted outside his home after he discovered the payments and reported them to his superior, whom he also claims was on the take. When he went to the Argentinian justice department, Moran claims the lives of his family were threatened and his livelihood eventually ruined.
