ALARMING REVELATION: Long Island Student, 15, Linked to Swastika Drawing Had Explosives at Home — Police Point to Father

Cops investigating a Long Island teen over a swastika scrawled in his high school found homemade bombs in his home — and busted his dad for buying the dangerous chemicals used to make them, according to authorities.

The 15-year-old student allegedly drew the hate symbol at Syosset High School, prompting Nassau County police to visit his home at around 1:30 p.m. Wednesday, when they found “several chemicals” that had been “combined to make explosive materials,” the department said.

Investigators found multiple acids, oxidizers, and bomb-making tools at the home — including Nitroglycerin — a highly unstable explosive popularized in video games like “Hitman: World of Assassination,” officials said.

The teen was arrested alongside his father, Francisco Sanles, 48, who prosecutors said used his credit cards to purchase “some of, if not all, of the chemicals” for his son on “multiple occasions.”

The teen, according to police, told investigators that his father was under the impression the chemicals were being used to “build rockets.”

After finding the homemade bombs, police shut down Patricia Lane — a quiet, residential street, for much of the day, as video showed several unknown chemicals being removed from the home and lined up in the front yard, according to prosecutors.

The bomb squad said the chemicals were too hazardous to move as they had been combined to create explosives and destroyed them on site in controlled demolitions.

Neighboring houses shook, and a loud boom was heard as the various chemicals were safely exploded.

The elder Sanles was charged with two counts of criminal possession of a weapon, two counts of criminal facilitation, two counts of endangering the welfare of a child, and reckless endangerment.

He was arraigned Thursday and pleaded not guilty to all charges. He was being held in Nassau County jail on $100,000 bail.

His attorney said Sanles “vehemently denies” all of the charges.

His son — who was not otherwise identified bacause of his age — was charged with two counts of criminal possession of a weapon, criminal mischief, aggravated harassment and making graffiti.

He is due to appear in family court separately on Thursday.

The FBI helped with Wednesday’s investigation, but said the case is now in the hands of Nassau County deputies.

The alleged hateful and antisemitic drawing that led police to the explosive discovery comes less than a week after The Post revealed antisemitism in the region is rising as 15% of Long Islanders now believe the Holocaust was exaggerated.

The school district sent an email to students and staff on Wednesday night following the incident.

“I am writing to inform you that the District found swastikas and racial epithets above urinals at Syosset High School. The District immediately commenced an investigation and notified the Nassau County Police Department,” the statement read.

“Our investigation identified the person responsible and this is now a criminal matter with an active police investigation. We are cooperating fully with our partners in law enforcement and remain in constant contact with them as their investigation continues,” the statement continued.

“This student will also face serious consequences pursuant to the District’s Code of Conduct. Antisemitism and hate speech have no place in our communities or in our schools,” it went on.
