NEWARK, N.J. (AP) -- The FBI and other law enforcement are investigating white powder that was mailed to businesses near the site of Sunday's Super Bowl. A federal law enforcement official says one had baking soda.
New York City police likewise say preliminary tests show no threat is posed by white powder that's been found in a letter at former New York City Mayor Rudolph Giuliani's Manhattan company. In New Jersey, Carlstadt Police Detective John Cleary says suspicious mailings went to at least five hotels.
The federal law enforcement official, who wasn't authorized to comment publicly and spoke on condition of anonymity, says powder from one envelope tested positive for baking soda. It's not clear where that letter was sent.
Hackensack University Medical Center has received a number of people for evaluation because they came in contact with the letters, but a hospital spokeswoman says there are no reported illnesses or injuries.
