A video posted Thursday on Twitter shows a white man harassing his black neighbor because he doesn’t believe he lives in the apartment complex.

“What are you doing in my building?” the white man asks. “You don’t live here.”

Chika Okafor, who works for the sports website Bleacher Report, posted a video of the confrontation, saying that it took place the night before. He wrote that the man in the video “interrogated” him while he was waiting for a Lyft on the first floor of his apartment building with a friend, who caught the whole exchange on video.
