The 20-year-old sparked a police investigation after posting a video to his Instagram account on July 11 that showed him firing a semi-automatic rifle. In the post, Reardon tagged the Jewish Community Center of Youngstown and identified himself as a white nationalist in the caption.

James Patrick Reardon of New Middletown, Ohio, is being held in the Mahoning County Jail on charges of telecommunications harassment and aggravated menacing. His bail has been set at $250,000.

A white nationalist was arrested Saturday for threatening to shoot up a Jewish community center in Youngstown, Ohio, police said.

The FBI Violent Crimes Task Force raided Reardon’s home on Friday and seized dozens of rounds of ammunition, semi-automatic weapons and a bulletproof vest, reported WYTV. They also reportedly found anti-Semitic and white nationalist propaganda.

“This is a person who has declared himself as a white nationalist and with the hate crimes, everything else going on, we wanted to make sure we did our part to make sure this person was taken off the streets very quickly,” New Middletown Police Chief Vincent D’Egidio told the news outlet.

Reardon attended the deadly Unite The Right rally in Charlottesville, Virginia, in 2017 and identified himself as a white nationalist while being interviewed for a documentary, D’Egidio said.

Reardon’s Instagram account, which featured multiple anti-Semitic posts, remained active until Sunday morning. When HuffPost reached out to Instagram for comment, a company spokesperson said the account had been deactivated.

“This account was disabled for violating our policies,” they said. “There is no place for hate, violent or extremist content on our services.”

The spokesperson declined to comment on whether Reardon’s account or any of his posts had been flagged before deactivation.

Neither the New Middletown Police Department nor the FBI immediately returned HuffPost’s requests for comment.

Reardon is scheduled to be arraigned Monday at Struthers Municipal Court.
