CARLSTADT, N.J. - Nothing toxic has been found in any of the envelopes containing a white substance that was mailed to hotels near the site of Sunday's Super Bowl, and to ex-NYC mayor Rudolph Guiliani, CBS New York reports.
A federal law enforcement official said one of the envelopes contained baking soda, according to the Associated Press.
The Bergen-Record reports police have determined that in at least one instance, the substance was found to be cornstarch.
New York City police likewise say preliminary tests showed no threat from white powder that was found in a letter sent to former mayor Giuliani's company in Manhattan.
Police were called to his consulting firm near Rockefeller Center after a worker opened the suspicious letter addressed to Giuliani around 10:30 a.m. Friday, police said. Eight mailroom workers underwent decontamination as a precaution.In New Jersey, the suspicious mailings went to at least five hotels, Carlstadt Police Detective John Cleary said.
The federal law enforcement official, who wasn't authorized to comment publicly and spoke on condition of anonymity, said powder from one envelope tested positive for baking soda. It's not clear where that letter was sent.
Hackensack University Medical Center received a number of people for evaluation because they came in contact with the letters, but a hospital spokeswoman said there were no reported illnesses or injuries.
The mailings arrived at an Econo Lodge in Carlstadt, a Homestead Inn in East Rutherford and a Renaissance Inn in Rutherford, Cleary said. Investigators intercepted additional envelopes from a mail truck before they reached a Holiday Inn Express and Hampton Inn in Carlstadt, he said.
The hotels reported to have been sent powder-filled envelopes are all within a few miles of Met Life Stadium in East Rutherford, N.J., where Sunday's Super Bowl will be played.\
