Philadelphia police said that they have closed their investigation into a claim that the famous Flyers mascot punched a 13-year-old boy during a Nov 19 event at the Fargo Center.

The incident was first reported by The Philadelphia Inquirer in January. Flyers season-ticket holder Chris Greenwell told the Inquirer that his son, Brandon, "playfully patted" Gritty on the head after their photo was taken at a November event and walked away. Greenwell said Gritty left his chair, "took a running start" and "punched my son as hard as he could." Greenwell said his son was diagnosed with a back bruise, and provided the Inquirer with documents from a chiropractor. He filed a police complaint on Dec. 21.

Gritty has not kept a low profile since news broke of the investigation. He made several public appearances, and traveled to St. Louis for NHL All-Star Weekend in January where he took the ice for the Mascot Showdown.
