KCBS reports that this afternoon an Uber driver was arrested following an incident of road rage involving a cyclist at around 1:30 p.m. in Fisherman's Wharf.

The Uber driver, 38-year-old Emerson Decarvalho of Daly City, was booked into San Francisco County Jail and is being charged with assault with a deadly weapon.

Police say that, for whatever reason, the bicyclist in question began screaming at Decarvalho, approaching his Toyota Camry on his bike, pounding the window and eventually pushing his side-mirror in.

According to police, after a loud argument, the bicyclist pedaled away but was struck and knocked off his bike from behind by the Camry. His lung was punctured and his ribs and collar bone broken. While the cyclist was transported to the hospital, Decarvalho remained at the scene and was subsequently arrested.

This incident is of course one of many, at this point, of Uber/Uber X drivers have behaved badly in various locales — to the point that even Funny or Die has parodied them. But when you have tens of thousands of non-employees roaming the Bay Area in vehicles, some bad apples are bound to slip into the bunch.

Update: Uber was quick to send this official statement: "Our thoughts are with the victim of this terrible incident. We are gathering more information, have reached out to the San Francisco Police Department and will assist their investigation however we can."
