Police say Jones -- who patrols the streets of Seattle in a black and gold superhero costume and bullet-proof vest -- assaulted a group of people who were "dancing and having a good time." Jones says they were fighting.

Police have also unveiled Phoenix Jones -- who has made TV appearances on Good Morning America and appeared in GQ magazine in disguise -- as Benjamin Francis, a husband and father of two.

Officials say he pepper sprayed the group at 2:30 a.m. on Sunday morning. He was charged with assault.

"In this particular case, he perceived that this group was fighting and when we contacted them, they said they weren't fighting," Det. Mark Jamieson, a Seattle Police Department public information officer, tells ABC News. "Unfortunately, he used force. He committed a crime, an assault against these individuals. That's against the law."

In a video posted on a journalist's Facebook page, it's unclear whether the group is fighting or dancing.

The police report says that Francis "has had a history of injecting himself in these incidents. Recently there has been increased reports of citizens being pepper sprayed by [Francis] and his group." Jones is a member of the Rain City Superhero Movement.

Jones' spokesman Peter Tangen, said that police couldn't have known the group was dancing and joking around instead of fighting if they were not on the scene.

"The first thing Phoenix did was to scream out to call 911," Tangen told ABC News. "He's been doing this four or five nights a week this entire year and he has never been charged with a crime. To assert that he ran into a bunch of people dancing and pepper sprayed them is entirely inconsistent with what he has done consistently this entire year."

On Good Morning America in January, Jones said, "I'm definitely not going to let my fellow citizens be assaulted and not do anything."
