A former New York City high school teacher and his twin brother were charged Thursday with attempting to make explosives, in part by paying students to extract gunpowder from fireworks, officials said.
The two 27-year-olds had been forging explosive devices inside their Pelham Parkway apartment since last October - using gunpowder from fireworks as the base for their bomb-making, according to the complaint.
Christian was charged with unlawful manufacture of a destructive device and distribution of explosive materials to a minor, while Tyler was charged with unlawful manufacture of a device, according to Geoffrey Berman, U.S. Attorney in the Southern District of NY.
After he resigned, his brother Tyler returned Christian's school-issued laptop to the school.
"'WE ARE TWIN TOROS STRIKE US NOW, WE WILL RETURN WITH NANO THERMITE", the diary also stated.
Law enforcement obtained a search warrant and raided the Toros' Bronx apartment on Thursday, and found "over 30 pounds of chemicals, which taken together in certain combinations, constituted explosive precursor materials", officials said.
Also found was a yellow backpack which contained a purple index card with the handwritten message, "Under the full moon the small ones will know terror", the complaint said.
The investigation began with a December 4, 2017 bomb threat against the high school in Harlem, after which one student was arrested and Christian Toro, a teacher at the school, resigned.

He said: "If we use our phones we can't take pictures of the children and put it on the Stoke City Twitter or Facebook page". Man City offered its "heartfelt sympathy to all victims for the unimaginably traumatic experiences they have endured".

Tyler Toro has also been arrested in relation to the case.
On Feb. 8, Federal Bureau of Investigation agents interviewed Christian Toro at an apartment on Matthews Avenue in the Morris Park section of the Bronx, where the brothers live with a female relative, the complaint said.
New York Mayor Bill de Blasio said there is no evidence to suggest an ongoing threat to the city or its schools now that the two have been arrested, but he said agents are still investigating.
The teacher told authorities he had found the document while researching the 2013 Boston Marathon bombing and had never read it or built a bomb, according to the complaint. Christian Toro was released on bail two days later, according to city records.
Toro had been arrested by the NYPD on January 31 and was charged, among other things, of the rape of a victim under 17, according to the complaint. He then started having sex with one of them, and then encouraged her to call in a fake bomb threat to relieve her boredom. A friend of the accuser told the investigators that she had also been at the teacher's apartment.
Torres continued, "I think their mom did a great job raising them. Recently, one of them shaved their heads and grew a beard - but you don't think anything of it".
"I was just with them yesterday in the elevators", she said.
