The Federal Bureau of Investigation and other law enforcement agencies investigated a suspicious white powder that was mailed to at least five New Jersey hotels near the site of the Super Bowl, reports the Associated Press.
The Record reports that the substance delivered by mail to hotels in Rutherford and East Rutherford near MetLife Stadium was cornstarch.
No injures were reported with the incidents.
The AP report states that one of the envelopes contained baking soda and tests on a powder that was found in a letter sent to former New York City Mayor Rudolph Giuliani's company in Manhattan showed no threat.
Carlstadt Police Det. John Cleary says someone at an Econo Lodge found the substance in an envelope on Friday. The substance was also found at the Homestead Inn in East Rutherford and a Renaissance Inn in Rutherford.
