A well known, criminally violent individual who has roamed the streets of the Castro for years was seen on camera last week assaulting a tourist and then getting taken down by a nudist bystander.

The situation went down on July 2, outside of Philz Coffee in the Castro. The individual, dressed in colorful clothing and a head-wrap, was identified by police as 38-year-old Zero Triball — a person known to Castro residents and businesses for terrorizing the neighborhood for about five years.

The SF Standard picked up the video below, posted to a Facebook group by business owner Petros Fanourgiakis, who owns Mediterranean sweet shop and retailer Aegean Delights (545 Castro Street).

"They threatened my team with a blow torch after we locked the doors and they took a chain to the window and door after they were locked out," Fanourgiakis writes. "Nothing broken, small win."

In the video, you can see the individual, Triball, speaking to a bearded man, identified as a Brazilian tourist. A bystander runs up behind Triball to snag the blowtorch he has in his hand, which he was allegedly threatening to use on the tourist's face. Triball then lunges and punches the tourist.

One of the neighborhood nudists, a longtime regular of the sidewalks on sunny days, Lloyd Fishback, can then be seen punching Triball and knocking him to the ground.

It sounds like he says, "You don't get to do that, asshole."

Fellow nudist Pete Sferra of San Jose confirmed to the Standard that Fishback and two other people subdued Triball and called police.

The Bay Area Reporter had a December 2022 report on Triball's previous assaults in the neighborhood, including numerous reported assaults in 2020. Longtime Castro neighborhood resident Greg Rojas said he was prepared to testify about Triball attacking him on Halloween in 2022, and business owners like Terry Asten Bennett of Cliff's Variety had stories about Triball assaulting or threatening her or her employees.

Bennett tells the Standard this week, "“He’s a known problem in the neighborhood. He’s erratic and violent."

It seems clear that whatever legal action took place against Triball last year, he is back on the streets and back in the Castro.

Prior to a hearing in the case — in which Triball faced 15 separate counts ranging from vandalism to assault with a deadly weapon — Supervisor Rafael Mandelman told the BAR that he and others wanted to "let this judge know that Triball has a long and problematic history in the Castro, his behavior has impacted a lot of people, and that he does not seem to be somebody who can be released into the community without it being a significant public safety risk."

Triball is facing a charge of assault with a deadly weapon, and possibly other charges.
