New York City's hate crime task force has launched an investigation after a woman tried to set a fire outside of a Brooklyn yeshiva on Thursday. Images released by the NYPD on Friday show the arson suspect dressed in dark clothing walking outside the metal gates of the Yeshiva of Flatbush around 7:30 p.m. Thursday as she dumped the gasoline out of a red container, police said. The woman then lit the fuel on fire and ran off. A security guard for the Jewish school was able to douse the flames with water. No injuries were reported. Mayor Bill de Blasio condemned the "vile" act in a tweet, calling it an "attack on all New Yorkers" and vowing to bring the perpetrator to justice. A reward up to $3,500 is being offered for information leading to an arrest.
