Gunshots rang out in the area of Fourth Avenue and 17th Street SE late Monday night, and police haven’t been able to determine who was involved.

About 11:15 p.m., a nearby Cedar Rapids police officer heard the shots and went to the area. Witnesses said one group of people outside of 377 17th Street SE, a home converted into apartments, started running down the block either chasing or being chased by another group of people, and one of the groups firedĀ the gun. Everyone was apparently wearing dark clothing.

No one involved has been identified.
