Cedar Rapids police say multiple people were involved in a shooting in downtown Cedar Rapid. The incident happened near 1st Avenue and 2nd street.

No one was injured during the shooting.

Police say someone opened fire around 1:40 a.m. near a parking lot. A TV-9 crew on the scene saw broken glass on the ground and officers searching the parking lot for shell casings.

One man said he was at a downtown bar on 2nd street when he heard the shots.

"I heard about eight shots, and I know what eight shots sound like cause I'm a California native. I know what shots look like, so I looked around and I was like why's everyone running and everyone was screaming and panicking," Steven Munoz said.

Authorities say they don't have anyone in custody. The shooting is under investigation.
