CHICAGO (CBS) — Four men were shot when a fight erupted during a hip-hop show at a Logan Square bar early Wednesday.

Police recovered two guns from the club.

But so far, they say they’re still working to figure out who pulled the trigger.

Police say those shots were fired overnight around 12:30 p.m., after a fight broke out inside the Ultra Lounge. 2169 N. Milwaukee Ave..

Four men were injured by that gunfire.

One of them took himself to a nearby hospital for treatment.

Police say the club was rented out for the night for a hip hop party by a group of young men.

They haven’t said if they know what that fight was about.

By the time officers got here, the group involved–other than two of the victims—was gone.

None of the injuries was believed to be life-threatening.
