An UberX driver, a ridesharing service which uses its own smartphone application to connect passengers with drivers of vehicles for hire, in San Francisco, CA., has been arrested for allegedly hitting a passenger in the head with a hammer after complaints were made as to his choice of route.

Patrick Karajah pleaded not guilty to two counts of assault with a deadly weapon and battery with serious bodily injury, according to the San Francisco District Attorney's Office.

The passenger questioned the route Karajah was taking, which sparked the disagreement, sources said. Karajah then pulled the vehicle over in the area of Alemany Boulevard and Ellesworth Avenue in San Francisco. Karajah then pulled out a hammer and started hitting the passenger on the head before fleeing the scene in the car, sources told NBC Bay Area.



Uber spokesperson Eva Behrend provided the following statement in response to the alleged attack:

"Safety is Uber's No. 1 priority. We take reports like this seriously and are treating the matter with the utmost urgency and care. It is also our policy to immediately suspend a driver's account following any serious allegations, which we have done. We stand ready to assist authorities in any investigation."
