A father and his teen son were arrested in Nassau County after what started as a bias incident investigation at Syosset High School led the police to discover chemicals that had been combined to create explosive materials inside the father's and son's home.
Nassau County police said they were investigating after a 15-year-old male, who was not identified because of his age, drew a swastika in a male bathroom at the school.
During the investigation, officers responded to the teen's home on Patricia Lane in Syosset and discovered several chemicals that had been combined to create explosive materials.
Nassau County police had to evacuate the home and the surrounding area.
The Nassau County Fire Marshal, Arson Bomb Squad and Nassau County Police Emergency Service Unit all responded to the scene.
People in the area heard a loud bang as police were investigating.
A source told News 12 that police had to initiate a controlled ignition of a chemical, due to its volatility, out of an abundance of caution.
The Nassau County Hazardous Material Response Team also responded and carefully removed the hazardous material from the home.
Investigators said the teen's father, Francisco Sanles, 48, bought the chemicals on multiple occasions.
Nassau County police charged Sanles with two counts of 1st degree criminal possession of a weapon, two counts of 4th degree criminal facilitation, two counts of endangering the welfare of a child and reckless endangerment.
He will be arraigned later today at court in Hempstead.
Police also charged the teen with two counts of 1st degree criminal possession of a weapon, 4th degree criminal mischief, 1st degree aggravated harassment and making graffiti.
He will be arraigned at Nassau County Family Court in Mineola.
