Speaking at the scene, LA Fire Department captain Adam Van Gerpen stated: "This morning, about 2am, firefighters were dispatched out to a traffic accident.
"On arrival, they found that we had a multi-casualty incident with a number of victims on scene. Our firefighters quickly realised we had a large number of patients, so we called for additional resources.
"Apparently, there was a vehicle which had somebody who lost consciousness inside the vehicle and drove into a taco cart, and then ultimately ran into a large number of people who were outside a club in East Hollywood."
