Self-styled Seattle crime fighter Phoenix Jones, who patrols the city's streets in a Batman-style costume, says he is back on the street after his arrest on charges of pepper-spraying a group leaving a nightclub.

Update at 1:09 p.m. ET: Seattle's self-styled superhero Phoenix Jones wrote on his Facebook page that he was back on patrol Monday night, the Associated Press reports.

Jones, whose real name is Benjamin John Francis Fodor, says he had to wear a backup costume after police seized his black and yellow outfit Sunday after his arrest for investigation of assault.

Jones is accused of using pepper spray on four people who were dancing after leaving a nightclub. He contends that he was trying to break up a fight, but the targets say they were just "frolicking" and he assaulted them for no reason.

Jones, who is due in court Thursday, spent about seven hours in jail before posting $3,800 bail, the AP says.

Original posting: Jones, who was arrested Sunday on four counts of assault, contends that he was breaking up a fight, although the people involved in the incident say they were only "frolicking" in the streets, The Seattle Times reports.

Jones, 23, told KIRO FM's Ron and Don Show that police confiscated his black-and-gold costume, but he has a backup and "should be on patrol later tonight," the Associated Press reports.

WATCH: A video of the incident.

Jones, whose real name is Benjamin John Francis Fodor, calls himself leader of the Rain City Superhero Movement and is often accompanied by a videographer who captures his crime-fighting escapades.

Although "Phoenix" has remained anonymous for months, The Seattle Weekly and The Smoking Gun reported after his arrest that Fodor is actually a mixed martial arts fighter who sports a bleached flat-top in the ring.

Jones, of course, has a Facebook page, where he claims he is a symbol "that the average person doesn't have to walk around and see bad things and do nothing."

In the latest incident, The Times quotes Seattle police spokesman Mark Jamieson as saying an officer on the scene determined "there was no fight."

In a 14-minute video, Jones is seen rushing into the crowd, shouting, "Break it up." He pepper-sprays the group, prompting a woman to chase him, swinging her high-heel shoe and shouting, "What are you doing?"

Jamieson says "it's fine" for people who want to dress up and walk around "but our concern is when they insert themselves into these potentially volatile and unknown situations."

"If you're deploying pepper spray on people on the street, you have to have a good reason to do it, or you'll be arrested for assault," he says.

Police have largely tolerated Jones for months, but a police report of the latest incident notes, "There have been increased reports of citizens being pepper-sprayed by (Jones) and his group," the AP reports.

The report says that although Jones has been advised to report incidents to police, "he continues to try to resolve things on his own."
