ST. PAUL, Minn. (AP) - A reporter at the Pioneer Press received and opened a suspicious envelope labeled "anthrax" on Saturday.

St. Paul police are investigating the envelope that contained a CD with a photo of Colin Powell labeled "Anthrax Shock and Awe Terror" and a white, sugar-like package taped to the top labeled "Anthrax" and "Biohazard."

The incident follows a string of anthrax scares at other newspapers across the United States, including the Star Tribune in Minneapolis. Police reported the Star Tribune received a package labeled "anthrax" on Thursday.

A California man was arrested Wednesday on suspicion of sending more than 120 hoax anthrax letters nationwide.
