DENVER (KDVR) — During a Colorado Rockies game against the St. Louis Cardinals at Coors Field, one fan decided to make a scene.

Update (April 13): Police have released a photo of a suspect and are asking for the public’s help identifying the person.

A viewer, CorinnaD, provided FOX31 with the video in the player above of the Rockies mascot, Dinger, dancing on the dugout with its back to the crowd when someone in the stands jumps up and blindsides the dinosaur.

According to the viewer, Dinger was back out on the field during the game after the incident.

Thursday morning, the Denver Police Department responded to a tweet containing the original video. DPD said an investigator was looking into this and wanted to speak with the person who recorded the video.
