We're told white powder was found today in a letter addressed to the River Park Nursery School on Amsterdam Avenue on the Upper West Side. The school also received a letter with white powder Tuesday. The NYPD says that a total of five schools have been targeted over the past eight days.
The NYPD says the letter sent to the schools have all had a powder in the envelope determined to be a non-hazardous powder. Investigators say it appears the motive is to cause disruption and alarm. So far, no arrests have been made.
