Four people were injured from a shooting inside the Ultra Lounge in the Logan Square neighborhood.
The incident happened around 12:30 a.m. Wednesday.
A neighbor reported hearing five gunshots, then seeing people flooding out the doors.
A 29-year-old man showed up at nearby hospital and said he’d been shot at a different location about the same time but police said nobody called to report that shooting, and believe he was shot inside this club.
Three other men – 24, 26, and 33 – were taken to Advocate Illinois Masonic Medical Center.
The four are all in stable condition.
The club was rented out for the night by a group of young men from the South Side.
A van trying to leave the scene was stopped by police in the driveway to the club’s parking lot.
Officers recovered two guns from the scene; they are also questioning potential witnesses.
