Six hotels near the New Jersey stadium hosting the Super Bowl have received envelopes containing a suspicious white powder, NBC 4 New York has learned.
A law enforcement source tells NBC 4 New York that the hotels, none of which are housing the teams playing at MetLife Stadium, received the envelopes Friday.
Two other suspicious envelopes were discovered at nearby post offices. The message in all eight envelopes was similar, the source said. One location in Manhattan also received a suspicious envelope.
One official told NBC News that an initial field test on one letter showed the white powder to be baking soda.
The FBI in Newark said the Joint Terrorism Task Force and hazmat units were responding, and said no injuries had been reported.
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 in juries.
