NEW YORK (1010 WINS) – A seventh school in Manhattan has received a suspicious envelope containing a "white powdery substance," the NYPD said Monday.
The Spence School on the Upper East Side received an envelope filled with white powder around 10:40 a.m. on Monday, police said. Emergency responders ultimately deemed the powder non-hazardous, the NYPD said.
Six other schools in Manhattan have also received suspicious envelopes containing a white powdery substance since March 10, according to the NYPD. Police said the contents of those envelopes were also deemed non-hazardous.
"Each envelope has a U.S. flag stamp and a handwritten address in block letters," the department said Friday. "The NYPD is sharing an example of the envelope for awareness."
“It appears that the motive of the sender is to cause disruption and alarm,” police said in an advisory on Thursday.
Police sources told WNBC that three of the envelopes were sent to schools on the Upper West Side: Montclare Children's School, River Park Nursery School, and NY Kids Club and New York Preschool.
Two packages were reportedly sent to Sen. Robert F. Wagner Middle School on the Upper East Side and Success Academy High School of the Liberal Arts in Midtown. It wasn't immediately clear which school received the sixth envelope.
Police said anyone with information about the incidents is encouraged to contact the NYC Terrorism Hot-Line at 888-NYC-SAFE. Anyone receiving a suspicious package should call 911, police said.
The following bulletins from the NYPD Counterterrorism Bureau’s Shield Unit advise on how to handle suspicious packages.
