The F.B.I. has arrested a Florida man who threatened to “exterminate” gay men and lesbians.

Fifty-year-old Craig Allen Jungwirth of Wilton Manors, considered an LGBT-friendly city, made the threats on Facebook.

“None of you deserve to live,” he wrote, according to a criminal complaint released by the bureau. “If you losers thought the Pulse nightclub shooting was bad, wait till you see what I'm planning for Labor Day.”

The Pulse is the Orlando gay nightclub where 49 people died and dozens were injured in a mass shooting in June.

“You can never catch a genius from MIT and since you faggots aren't dying from AIDS anymore, I have a better solution to exterminate you losers,” he wrote in a separate post. “It's time to clean up Wilton Manors from all you AIDS infested losers.”

The Florida Highway Patrol arrested Jungwirth on an unrelated charge on Saturday.

Since Facebook does not have servers located in Florida, Jungwirth is charged with transmitting an interstate “threat to injure the person of another.”

According to an unconfirmed report, Jungwirth was hospitalized some time after his arrest.
