The SFPD's Traffic Safety division announced Wednesday that it had seized a vehicle believed to have been involved in "an illegal exhibition of speed event," a.k.a. a sideshow, last month.

The sideshow happened on July 11 at the intersection of Barneveld and McKinnon avenues, in the industrial area between the 101 and 280 freeways west of the Bayview. A photo apparently snapped from a participating car showing a dark-haired woman hanging out of the window of a Cadillac holding an AK-47 assault rifle was posted to social media and subsequently used as evidence by police.

The SFPD said in a tweet that the traffic division "worked up a case" and the suspect vehicle, that Cadillac, was seized on Wednesday. On Twitter they shared the AK-47 photo alongside a photo of the car being towed.

There's no further information yet about any arrests being made, or, for instance, possible gun charges being sought.

Though a San Diego-based, Republican-appointed federal judge overturned California's decades-old ban on assault weapons back in June, the 9th Circuit issued a stay of that decision several weeks later, and AK-47s remain illegal in the state.

Following a large sideshow in San Francisco in September 2020, the SF Board of Supervisors passed legislation that allows the SFPD to impound cars suspected of being involved with sideshows for two weeks or up to 29 days.
