Second anthrax scare in Montgomery, Alabama

A second anthrax scare at Montgomery, Alabama's municipal court building is not, the FBI has said, related to a string of similar letters sent to congressional offices around the state.

That determination was made by investigators following the reception of another white powder containing letter by the Mobile, Alabama, office of U.S. Sen. Richard Shelby on Tuesday.

"It came from an individual purporting to be paying their traffic ticket to the municipal court," Strange told the New York Times. "When the employee opened the envelope this white substance fell out of it."

No injuries were reported by the six employees exposed to the letter.

Nine suspicious envelopes were found Sunday and Monday at congressional offices, FBI spokeswoman Angela Tobon told the New York Times.

Workers in Montgomery were evacuated and a HAZMAT team was brought in to deal with the Tuesday letter. The powder in the letter, Montgomery's fire department has said, was found to be baking soda. The court building was then reopened later Tuesday afternoon.

The powder in the other nine letters has been found to be a common household sweetener.

The Montgomery letter came from out of state, Mayor Todd Strange said, and the nine previous letters where mailed from within Alabama.
