Police are investigating after fireworks exploded outside the homes of two rabbis in Rockland County this week, police say.

A woman heard a loud boom outside of her home on Tarry Hill Drive in New City around 10:45 p.m. on Tuesday night. When she went to see what the noise was she saw four young men or teenagers running outside of her home. One of the men then threw a firework at her home. It exploded next to a tree and caught the tree on fire, according to police.

As police investigated, they were told that a similar explosion occurred at a neighboring home on Phillips Hill Road. People were gathering at the home when they heard a loud boom coming from the driveway. They went to see what caused the noise and found a firework between three parked cars.

The first explosion apparently occurred outside the home of Avremel Kotlarsky, the Director of Chabad. The second explosion was outside the home of Rabbi Simcha Morganstern, an associate rabbi at the Chabad of Rockland, according to the Anti-Defamation League of New York.

Police said they are looking for video surveillance evidence and increasing patrols in the area.

Investigators ask anyone with information to call the Clarkstown Police Department at 1-845-639-5840.
