The man police believe was responsible for $2,000 in damages to a Zipcar in this road rage incident during a Critical Mass event in the Marina last month has been found. As the SFPD reports in a press release, on Saturday they arrested one Ian Hespelt, 39, of San Francisco and charged him with vandalism, false imprisonment, assault with a deadly weapon, and maliciously and willfully throwing a substance at a vehicle.

Officers were on bike patrol in the vicinity of AT&T Park during the Billy Joel concert when they say they recognized Hespelt and his bike from the infamous YouTube video from August 28, which has since gone viral. The man was seen in screencaps to have a handlebar mustache, and to be wearing, ironically, a t-shirt that said "non-violence is our strength." The SFPD says they are not releasing a booking photo yet "due to pending identification matters."

The Chronicle reports that Hespelt is "a Macy’s employee in San Francisco and a shop steward for the United Food and Commercial Workers Union” took part in union protests, according to the American Postal Workers Union. He's pictured on the site with his mustache, and quoted as part of a protest against the company Staples, which had begun staffing mini-post offices in its stores with low-wage, non-union, non-USPS employees. Though not a postal worker himself, Hespelt was passionate about joining the fight, saying, "I am a firm believer of the power of numbers... If more people show up, you can only ignore them for so long. Pitching in to help out another union makes us all that much stronger."

Also, ABC 7 reports that Hespelt has a felony warrant out of Washington State on drug charges. They also report that the female victim whose Zipcar took the brunt of Hespelt's rage ID'd him in a photo lineup.

After being questioned on Saturday evening, Hespelt was booked on the above charges, along with a misdemeanor charge of inciting a riot.

More on this when Hespelt has his day in court. And here's the video again, to refresh your memory.
