Madison Police discovered two injured men after being called to a fight early Saturday morning.
Officers responded to the BP at 318 S. Park St. around 3:00 that morning.
A witness said multiple combatants jumped out of several vehicles and the violence took place in the parking lot.
A second witness said one victim was being kicked repeatedly in the head by a group of young men.
There were also reports of glass bottles being thrown.
Police found two unconscious men. One was inside of a car, while the second was on the pavement.
The second was taken to the hospital with a concussion.
Many fled before police arrived, and those still on scene were reluctant to give detailed information about the fight.
