The NYPD Counterterrorism Bureau said it's "closely monitoring" the situation.
A senior law enforcement official tells NBC New York the FBI is sending criminal and counter-terror investigators to Rockland County to assist local authorities.
The attack comes on the heels of half-a-dozen hate crimes across New York City in recent weeks that targeted the Jewish community.
Mayor de Blasio said Friday that police presence would increase in Crown Heights and two other Brooklyn neighborhoods with large Jewish populations.
New York State Governor Cuomo issued a statement shortly after midnight that read in part, "This was a despicable and cowardly act, and I am directing the State Police hate crimes task force to immediately investigate and to use every tool available to hold the attacker accountable to the fullest extent of the law. State Police are currently on the scene assisting local law enforcement."
