The Federal Bureau of Investigation and the New York City Police Department are investigating anonymous letters threatening Mayor Michael Bloomberg that tested positive for the deadly chemical ricin.
The writer of a letter opened in New York on May 24 threatened the mayor and made references to “the debate on gun laws,” NYPD spokesman Paul Browne said yesterday in a statement. The letter was opened in a biochemical containment box, which is part of the screening process for mail addressed to the mayor’s office, and mailroom employees weren’t infected, according to a memo today to employees in the office.
