A 90-year-old Florida man was arrested this week after he allegedly pointed a handgun at a man working at the post office and threatened to "blow his head off."

Officials said the suspect, who has been identified as H.B. Shea, was dissatisfied with the service at a post office located at Via Ancho in Boca Raton on Monday, reported The Washington Post. As a result, he threatened the U.S. Postal Service employee with his firearm.

The Palm Beach County Sheriff's Office released a statement on Facebook about the incident, saying that Shea was "not satisfied with the services" at the post office.

"He was not satisfied with the services so he pulled out a handgun, pointed it at the Postal employee and threatened to 'blow his head off.' As the suspect was exiting the post office he was taken into custody without incident by the responding deputies. The firearm was recovered and placed into evidence," reads the statement.

Before being taken down to the county jail, Shea was first transported to the West Boca Medical Center for a medical evaluation, reported WPBF. He was then booked into the Palm Beach County Jail on the state charges of aggravated assault with a deadly weapon.

In addition to being charged with aggravated assault, he has a pair of weapons counts and could also face a federal charge related to his carrying a handgun into a post office, according to The Smoking Gun. Federal postal police are expected to file charges of bringing a gun into a postal facility. The Palm Beach Sheriff's Office will handle the investigation.

The man turned 90 in May and lives near the post office in a condominium development
