A video showing an NYPD officer launching a foul-mouthed tirade at an Uber driver who honked his horn at him is being investigated by the NYPD Internal Affairs Bureau.

The footage shows a plain clothes officer swearing at the driver for apparently honking his horn at the unmarked police car after the officer tried to park without indicating.

The officer repeatedly mocks the mild-mannered driver’s accent and intersperses the tirade with numerous uses of foul language.

“I don’t know what f*****g planet you’re on right now” he yells at the driver before slamming the door.

Before he returns with a ticket for the driver, Sanjay Seth, the passenger who filmed the incident, describes the officer’s behaviour as “crazy” and “really inappropriate.”

The officer then returns, continues his rant and asks the driver: “How long have you been in this country for?”

He tells the driver that the only reason that he isn’t taking him to jail is “because I have things to do.”

Seth, who posted the video to his Youtube channel, wrote that the incident took place in the city’s West Village, within the confines of the city’s 6th precinct.

A statement from the NYPD said: “We are aware of the incident and video and it is under review with the department’s Internal Affairs Bureau.”

As of last week, Uber taxis officially overtook the number of registered taxis in the city.
