A hate graffiti investigation at a Long Island high school has turned into a major criminal case after authorities say they uncovered homemade explosive materials inside a student’s home.

According to the Nassau County Police Department, officers were initially called to Syosset High School after a swastika and racial graffiti were discovered inside the building. The investigation led police to the home of a 15-year-old student, where authorities say they found “several chemicals” that had been combined to create explosive materials.

The teen and his father, identified by police as Francisco Sanles, 48, were taken into custody. Authorities allege the father “on multiple occasions paid for the purchase of the various chemicals” used in the materials.

Bomb squad officials determined the substances were too dangerous to transport and instead detonated them at the scene, with neighbors reporting a loud blast that shook nearby homes.

The elder Sanles faces multiple charges, including criminal possession of a weapon and reckless endangerment, while his son has been charged with weapons possession, aggravated harassment and making graffiti.

The FBI assisted in the investigation, which remains ongoing. School officials said the student will also face disciplinary action, adding, “Antisemitism and hate speech have no place in our communities or in our schools.”
