Fox News’ Geraldo Rivera took on a heckler who interrupted him as he delivered an on-scene report from Baltimore on Friday, calling him a worthless anarchist.

While explaining to Fox News host Sean Hannity that prosecutors were investigating a fourth unscheduled stop by the van transporting detainee Freddie Gray, Rivera stopped mid-sentence to confront the heckler.

“What’s your problem?” he asked the man, as the lights and camera shifted to the crowd of demonstrators.

At that moment, the heckler and other protesters around him stopped talking and turned away from the lights.

“You’re only brave when the cameras are turned?” Rivera taunted the guy. “You anarchist, you’re nothing. You ain’t nothing.”

Another onlooker who didn’t shy away from the camera asked Rivera why he was harassing the locals.

“These aren’t locals,” Rivera responded. “They’re ‘Occupy Here and There.’ They’re professional anarchists.
