Third possible anthrax case appears in Florida office

Reports say a third office employee in Florida was exposed to anthrax.

It is being reported that a female librarian at the American Media offices in Boca Raton tested positive for anthrax exposure.

Journalist Bob Stevens died as a result of anthrax bacteria last week.

David Pecker, president of American Media, said the librarian was already being treated for pneumonia when she tested positive for anthrax exposure.

Attorney General John Ashcroft says the Boca Raton case "could become a clear criminal investigation".

Officials say they have no evidence to suggest a terrorist act but they aren't taking any chances.

"We don't have enough information to know whether this could be related to terrorism or not," Mr Ashcroft says.
