Police are still investigating a report of a late-night fight in northeast Sioux Falls.

A report of two groups fighting, with shots fired, was called in around 11:30 PM Sunday from the 3600 block of East 6th Street, but when officers arrived they found no one was injured and that the people involved had fled.

Investigators say the parties knew each other and that the incident was part of an ongoing dispute.

Anyone with information is asked to call Crimestoppers.
