Jim Jones -- White Cops Harassed Me ... Because I'm Black

Jim Jones claims he was the victim of racial profiling at Newark Airport last week -- when he was pulled over by 4 white cops, who ordered him out of the car while they searched the vehicle for drugs ... and TMZ has the pic.

A rep for the "We Fly High" rapper tells us ... Jones was at the airport Friday, waiting to pick up a friend (who asks Jim Jones to pick them up from the airport?) when he was approached by a police officer who told Jim he smelled weed coming from Jones' car.

You can see in the pic ... four cops surrounded Jones while he was ordered out of the car and told to place his hands on the trunk. The cops searched both Jim's person and his car.

Jim's rep tells us ... cops didn't find a single piece of the green stuff -- but still issued Jim a citation for driving without a license.

Jim's rep says the rapper is furious over the incident -- explaining, "He was searched for nothing more than racial profiling."

A rep for the NY/NJ Port Authority tells us ... they were unaware of the situation and are currently looking into it.
