We broke the story, Brandon -- heir to the Davis oil fortune -- had a single car wreck in L.A. and absolutely destroyed his Mercedes Benz sedan. Davis was transported to a hospital, where police arrested him for an alleged DUI.
Earlier in the evening, Brandon was seen drinking wine with Comrie -- Hilary Duff's estranged husband -- at L.A. sushi joint Matsuhisa. It doesn't appear Comrie was in the car with Brandon at the time of the accident ... as the ambulance only transported one patient.
Davis, aka Greasy Bear ... has been released from the hospital, and is getting transported to jail.
