Tyga was seen being hauled away in handcuffs by police after leaving Hollywood's Avenue Nightclub on Tuesday night.
A spokesperson for the Los Angeles Police Department tells ET that during a traffic stop conducted in Hollywood, law enforcement noticed that the 27-year-old rapper's Mercedes G-Wagon had only paper plates. Officers also decided to conduct a field sobriety test upon stopping Tyga, born Michael Ray Stevenson, but due to the amount of paparazzi in the area, they instead put him in a patrol car and transported him to a local station, where he took a field sobriety test and passed.
Police then released Tyga and he was cited for a minor traffic violation.
While with police, the paparazzi asked Tyga if he thought they were racially profiling him. "'Cause I'm a good looking rapper," he responded.
An eyewitness tells ET that Tyga did not seem mad or upset.
Earlier that day, Tyga posted some photos to Instagram of his new Mercedes G-Wagon.
While Tyga was having a slight run-in with law enforcement, Kylie Jenner -- who's been in an on-again, off-again relationship with the rapper for years -- was also out and about in Los Angeles, making an appearance at the PrettyLittleThing Campaign launch.
Earlier this week, it was announced that the 19-year-old reality star landed her own show, though it's not yet known if Tyga will make an appearance on the docu-series. Here are more details on Life of Kylie:
