Late Tuesday night, Black students at Kean University received death threats via Twitter during a campus sit-in.

A user named @KeanUAgainstBLK wrote a series of racist and violent tweets aimed at Black students participating in Camp Night Out, a peaceful demonstration to draw attention to racism on campus. The account posted tweets such as, “i will shoot any black person I see at kean university” before students discovered the account and spread the tweets on social media.

Many students were not satisfied with the university’s response. Some asked for escorts to class, while others suggested to not attend at all.

I’m asking Kean students as your student leader to not attend classes tomorrow as recent threats have been made against the campus. — Nigel Donald (@Nigeld906) November 18, 2015
