Violence erupts at North Avenue Beach on opening day.

North Avenue Beach in Chicago was closed on the first day of swim season after shots were fired, sending visitors running for cover. A group of young men got into a fight on the beach when someone pulled out a gun and started shooting. A 15-year-old was arrested as the shooter, and two weapons were recovered. No injuries were reported, but several people were taken to the hospital for intoxication. The incident occurred less than 24 hours after the city's Memorial Day weekend safety plan was announced, which includes an increased police presence across the city, including the lakefront.
