WARREN, Mich. -- Three teenagers accused of randomly beating innocent people in Mount Clemens faced a Judge Friday. Police arrested a 16, 14, and 18 year old, all from Clinton Township.

Police said they were among 20 to 30 people who attacked and robbed a motorist Saturday night may also be responsible for several other violent crimes that took place the same day.

Four people were taken into custody earlier this week for questioning after a motorist was beaten unconscious and left with a fractured skull.

Police said the incident took place when Andy Kauffman, 29, and his wife, Angelina, were driving on North River Road when more than two dozen men wearing ball caps and baggy shorts spread out across the street and blocked traffic.

Kauffman tried to drive past them and someone threw a brick in his window. Kauffman stopped his car and got out to see what happened.

"At that point at least 12 of the subjects jumped on him, beating and kicking him several times to the point where he was unconscious," Macomb County Sheriff Mark Hackel said. "A second man then got out of the car and also was attacked, but not nearly as bad as the first individual."

A short time later, police were called to a gas station nearby for a fight. The mob attacked two men in downtown Mount Clemens. One man ran to Desperado's bar to find safety, while the other man ran to a nearby gas station.

The victim at the gas station was attacked by the mob, but he was not seriously injured, police said.

The victim told local 4 he believes the attack was random because he did not know any of the attackers.

Police said there were several incidents within a few hours and they fear the same group of attackers was involved. A group of people were attacked at a nearby carnival before the motorists was beaten.

Anyone with information can call 586-469-5151. Police are still searching for other suspects.

Officers released the video of the mob responsible for the attacks.
