A Hialeah police officer was conducting a traffic stop on Friday when he noticed two men fighting in the street.
The officer quickly let the car he'd pulled over go and went over to break up the fight between two drivers who were in the throes of a road rage incident.
The incident took place in the 1200 block of West 49th Street.
When the officer went up to the combatants he saw Hector Herrera,24, holding a black baseball bat and the victim trying to prevent the bat from hitting him, a police report said.
The victim told the officer that Herrera became enraged when he didn't allow him to change lanes, the report said. The victim was then blocked by Herrera, who got out of his vehicle with the bat and smashed the victim's right side passenger window.
The victim became scared and attempted to drive away but crashed into Herrera's vehicle, which was blocking him, police said.
Another driver recorded the apparent case of road rage, and posted the video to a Facebook group called "Only in South Florida" on Saturday.
The video appears to show Herrera, the driver of a white truck, and the victim, who was in a white car, get out of their vehicles and get into a physical fight.
The victim was struck in the right shoulder with the bat, police said, and the fight continued in the street until the officer was able to break it up.
Herrera was arrested on an aggravated battery charge.
