According to the UCLA Police Department, the incident happened on Christmas Eve around 6 p.m.
The student was walking westbound on the north sidewalk of Weyburn Avenue when a black Mercedes-Benz convertible with four occupants drove up next to the victim, police said.
That's when police said one of the occupants yelled a homophobic slur at the student and another occupant threw wads of paper.
The victim was not hit by anything during the incident.
Police did not release a detailed description of the suspects, but said they're four men in their early 20s.
Anyone with information is urged to contact the UCLA Police Department.
