While on foot patrol on July 4th, 2022, an officer observed an explosion in the area of Gate A behind Heinz Field. The officer found that a nearby tent also had blast marks. 

Shortly afterwards, officers heard a second explosion along the river trail, which was determined to have come from a dumpster underneath the Mr. Rogers statue. Witnesses stated they saw someone throw an explosive into a dumpster. 

EOD and arson investigators arrived and processed the scenes. The investigation into both incidents is ongoing.
