Green Bay police blocked off downtown streets for three hours on September 11, 2026, to investigate a suspicious package. Officials confirmed the package contained an American flag and a letter regarding a flag at a bank in Hales Corners.
Why it matters
Law enforcement agencies frequently must treat any unidentified items with caution to ensure public safety in busy urban environments. The precautionary closure allowed specialized teams to determine the contents posed no threat to the community.
Hazardous materials teams and a K9 unit confirmed the item contained no explosives. The author of the complaint letter remains unidentified and the investigation is ongoing.
