Bomb and anthrax hoax at Camden building

The FBI is investigating a bomb and anthrax hoax at the U.S. District Court building in Camden.

A mail clerk opened an envelope Friday morning to find a letter claiming a bomb was in the building and the white powder inside the envelope was anthrax, said Juan Matos, the U.S. marshal for New Jersey.

The building was locked down and a K-9 unit scoured it. No bomb was found, and the powder tested negative for anthrax and other biological agents.

The letter is undergoing forensic analysis at a state police laboratory in Hamilton to identify the sender. - James Osborne
