A fire official says the second floor of the federal court building in Philadelphia was evacuated after authorities found a letter containing a threat about anthrax.

Crews responded to the federal court building in the city's historic district around 9:25 a.m. Wednesday.

Fire officials evacuated people from the second floor, but people on other floors remained in the building.

An official said a letter was found, but the investigation revealed it did not contain anthrax or any other dangerous substance.

The FBI has cleared the scene.
