FBI probes threats to Goldman Sachs

The FBI is investigating anonymous mailed threats against the Goldman Sachs investment firm but does not consider the warnings to be of high credibility, an investigator said in New York.

The letters, handwritten in red ink on loose-leaf paper and signed “A.Q.U.S.A.,” were mailed to 20 newspapers, authorities said. The letters contained the warning: “Hundreds will die. We are inside. You cannot stop us.”

A federal law enforcement official familiar with the investigation said the FBI “does not assign high credibility to the threat” because of the circumstances surrounding the letters, including their brevity and the nonspecific nature of the threat.
