When officers arrived, everyone went home, but came back a few hours later.
When Milwaukee Police and the Milwaukee County Sheriff's Department returned in riot gear, the kids started throwing rocks at authorities.
Officials said at one point one person threw a brick through a Milwaukee County bus at Sherman Blvd. and Locust St. Another kid broke a window at the BP gas station at 43rd St. and Burleigh St. Then, another kid broke a window on a police cruiser. Another kid then lit a gas can on fire and threw it into a garbage bin.
