PORT ST. LUCIE, Fla. (CBS12) — A Port St. Lucie man was arrested earlier this month after law enforcement officials say he sent emails that were interpreted as threats, prompting an investigation involving local police and the FBI.

According to a Port St. Lucie Police Department arrest affidavit, officers arrested Aria Asghari, 39, on January 9 at a residence on Southwest Indigo Inlet Lane. Asghari was charged with intimidation by written threat to kill or injure, a felony under Florida law.

According to the report, Asghari “expressed sympathy for mass shooters.” He also allegedly expressed that he was previously athiest, but became “super religious” and believed he was the next Messiah.

Police say the investigation began when the FBI notified a Port St. Lucie detective assigned to a special investigations task force about emails allegedly sent from an account associated with Asghari. Authorities reported that the content of the emails raised concerns about public safety and prompted further review by law enforcement.

The affidavit states that additional information came to light when Asghari, who is from Iran, allegedly contacted local road patrol units by phone, referencing the emails. Officers determined there was probable cause to believe the messages constituted a written threat under state statute, police said.

Detectives, accompanied by FBI agents, responded to the Indigo Inlet Lane address to make contact with Asghari. According to the report, Asghari declined to answer questions and requested an attorney. He was then taken into custody without incident, handcuffed, and transported in a marked police vehicle to the St. Lucie County Jail.

Police noted that no weapons were seized at the time of the arrest and that Asghari was not reported to be under the influence of alcohol or drugs.

Asghari was booked on Friday afternoon and is charged with intimidation — written threats to kill or injure, a second-degree felony, with a $5,000 bond.

He’s also being held under a law enforcement Baker Act.
