Pentagon agents raid Siemens in Malvern

"Criminal investigators with the Defense Department are searching the U.S. headquarters of Siemens Medical Solutions near Philadelphia," says the Associated Press.

"The Defense Criminal Investigative Service has agents on site Wednesday searching the office in Malvern. Special Agent-in-Charge Ed Bradley confirms the search is part of an ongoing investigation but is not commenting on the nature of the probe. He says agents will remain on site 'as long as it takes.' "

The company recently won a $267 million military radiology contract. The investigation is connected to a contract; Feds won't say which one, says Reuters in this updated story.
