The video shows a wild ride through San Francisco's Broadway Tunnel. It was posted on the Facebook page of San Francisco Police Sgt. Carl T. The sergeant wrote on his page, "100 Miles per hour in the Lambo," referring to a Lamborghini. The blog SFist reports he also commented that he and his friends "were all drunk."
The head of the San Francisco Police Officers Association says he's never seen anything like it.
"This would be on a case by case basis; if in fact it was an off-duty police officer driving the vehicle the chief of police would have to make a determination of whether or not discipline is appropriate," Gary Delagnes said.
There's no confirmation that the driver is Carl T. ABC7 News was unable to reach him Wednesday.
The sergeant has removed the video from his Facebook page and shut down the page entirely.
