DULUTH — The Duluth Police Department spent six hours in a standoff Sunday night in the Hillside neighborhood, but the 36 year-old suspect was gone before it started.

Officers went to the 700 block of East First Street around 6 p.m. to investigate a domestic incident in which a handgun reportedly was fired. The Tactical Response Team and Crisis Negotiations Team followed, creating a perimeter around the apartment, according to a news release. Nearby residents were evacuated.

Officers eventually reached him by phone and met with him just after midnight. The suspect, who hasn't been charged, was taken to the Public Safety Building.

The incident is under investigation.
