Rochester, MN (KROC-AM News) - Rochester police investigators were called out to a reported shooting early Sunday - at a residence that was visited by officers twice Saturday night.

A spokesman says officers initially went to the residence located on 9th street NW just off North Broadway to break up a loud party. They later returned after receiving more complaints and ordered everyone to leave.

And then calls came in around 1 a.m. Sunday about shots being fired. This time officers forced their way inside and found several intoxicated people - but no injuries.

The spokesman says officers were able to determine at least three shots had been fired from two different guns. One bullet went through a window in the home and another was found in the window frame.

The spokesman says no one at the residence cooperated with investigators and no arrests were made. The shooting remains under investigation.
