A former New York City school teacher and his twin brother were arrested and charged on Thursday after FBI and NYPD officers found bomb-making materials at their apartment, according to officials, who said they attempted to make an explosive device.

Law enforcement officials said at a press conference late Thursday that the probe is in its early stage. Mayor Bill de Blasio said there’s no “imminent threat” to the city.
