Police in New York City on Monday shut down a Hasidic Jewish school in Brooklyn after neighbors complained that more than 60 people had gathered inside.

The incident, the latest in a series of clashes between the NYPD and Orthodox Jewish communities, prompted a response from Mayor Bill de Blasio on Tuesday. De Blasio defended the decision to break up the school day, noting that no one had been issued a summons because once police arrived, school administrators had complied in sending the students home.
