YouTube video helped police in Colorado Springs make two arrests in a road rage incident.

Police said officers were called to a report of a hit-and-run on Nevada Avenue, near I-25, in Colorado Springs Monday night.

Officers said while they were investigating, they learned a witness videotaped the incident and posted it to YouTube.

"In the video you can see an altercation between the driver of a motorcycle and the driver of a car," police said. "The driver of the car swerves into the motorcycle causing the motorcycle to crash."

Denver7 spoke with the man who captured the road rage video on his dash camera.

"This is probably the worst thing I've captured on video," said Joel Hartzell.

Hartzell is a delivery driver in Colorado Springs and said he keeps his dash camera recording while he's at work.

"I had a dash cam installed and it was recording the whole time, I didn't expect anything to happen," he said.

Hartzell said he was on his way to drop off an order, when he turned around a corner and ended up behind the two drivers.

A few minutes later, he saw the driver of the motorcycle pull up next to the Mustang's window. Seconds later, the Mustang swerved and knocked the motorcyclist to the ground.

"It was pretty ridiculous from both parties," he said. "I feel bad because I'm not trying to get people charged, but at the same time we can't have that kind of activity on the roads."

Police said both drivers were arrested. The driver of the car, 21-year-old Brian Candelaria was arrested on suspicion of second degree assault. The motorcycle driver, 22-year-old Skyler Bradley, was arrested on suspicion of harassment.

Prior to his camera rolling, Hartzell said Bradley told him the driver of car tried to run his girlfriend off the road, which is what led up to the road rage.
