In the middle of this surreal Chicago road rage video, the crazed Audi driver reportedly recognized a former co-worker watching from the sidewalk: "He said, 'Hey, Eric.' He stopped right in front of our door and said, 'If you tell anybody, I'll kill you.'"

According to reports, the argument began when Martin Vigil, 48, left the scene of a minor accident. The other driver followed him, eventually getting out of his car and kicking Vigil's Audi. That's when Vigil apparently went insane.

The Audi drives off, but makes a U-turn and comes back into the video, striking the Camry head-on. The vehicle narrowly missed bicyclist as it rams the car again. The driver of the Camry delivers another boot to the bumper. A few more rams follow.

"He was very frazzled. He was screaming and he was hollering and people across the street were saying, 'Call the cops! Call the cops!'" Erickson Ocasio, witness, said.

Ocasio, whose camera recorded the confrontation, knows Vigil from the real estate business. Despite an alleged threat, he tipped off police.

"He said, 'Hey, Eric.' He stopped right in front of our door and said, 'If you tell anybody, I'll kill you,'" Ocasio said.

When WLS-TV contacted Vigil, he reportedly claimed he was the victim and declined to comment further. He's been charged with misdemeanor assault, leaving the scene of an accident and criminal damage to property.
