Christian Toro and Tyler Toro  "knowingly made firearms" and aided and abetted in the making of firearms at  their  home in the Bronx from about October 2017 to February of this year  according to a criminal complaint filed in the Southern District of New York.
 Christian Toro  is also accused of distributing explosive materials to two individuals under the age of 21 in the Bronx  according to the complaint.
On Dec. 4  2017  a student was arrested after a bomb threat was called into a high school in Manhattan's Harlem neighborhood  and  Christian Toro  resigned from  his  teaching position shortly after the arrest  the complaint states.
After the resignation   Tyler Toro  returned Christian Toro's school-issued laptop  where a technical specialist found a copy of the "Explosives Book " a text that provides instructions for manufacturing explosive devices  according to the complaint.
On Feb. 8 of this year  multiple law enforcement agents interviewed Christian Toro  who stated that he "had not intentionally downloaded" the incriminating book into the laptop. Instead   Christian Toro  stated that  he  had been researching the 2013 Boston Marathon bombings and had come across a copy of the book.
 Christian Toro  also told investigators that  he  never built a bomb and had only looked at the book's table of contents.
On Wednesday  investigators interviewed multiple students at the school  who indicated that at least two students visited an apartment where  Christian Toro  would pay them $50 per hour to break apart fireworks and store the powder that came out of them in containers  the court document states. The students visited the apartment between October 2017 and January 2018  according to the complaint.
Christian Toro and Tyler Toro both pleaded not guilty. Attorneys for the brothers were not immediately available for comment.
