From NYTimes - now the FBI is investigating the questionable Olympus deal:
The F.B.I. is now investigating the $687 million payment, according to two people briefed on the case. The focus of the investigation is not yet clear, and a spokesman for the F.B.I. in New York, James M. Margolin, declined to comment.
“We are not aware of any investigation” in the United States over the Gyrus deal, said Yoshiaki Yamada, a spokesman for Olympus in Tokyo. He said he could not comment further, including whether Olympus had been contacted by United States authorities.
Olympus continues to deny any "underworld links". The company's stock is currently trading at 1,190 (it was almost 2500 before the CEO Michael Woodford got fired):
