Officials added security at an Illinois high school after a student posted a series of racist comments online in response to the Ferguson protests.

"I don't feel sorry for black people,” the Oakwood High School student posted on Twitter at 10:16 p.m. Monday. “If you hate us so much GO BACH TO AFRICA. We should have never bought you.”

The comments were made shortly after the announcement that a Missouri grand jury had declined to indict the officer who shot 18-year-old Michael Brown, sparking protests and rioting in Ferguson.

“I mean this wouldn't happen if black people wouldn't act like hooligans,” posted the student, whose name was not released. “We don't start a riot when white ppl die.”

Her Twitter account has since been locked.

The student’s comment urging black people to go back to Africa was retweeted more than 3,700 times by the following morning and provoked a wave of angry responses.

“I'm the quiet one but this is disgusting,” replied one Twitter user. “Last time I checked my ancestors were not brought here freely. Ms I think you forgot about this called slavery. It's uneducated and ignorant people like this that makes the world a horrible place.”

Another Twitter user suggested, “DAMN let’s get her.”

The student’s name, school, and phone number were posted on Tumblr, and school officials posted law enforcement officers Tuesday at the high school in response to the widespread attention to the girl’s comments.

They will reassess the situation before classes resume Monday following the Thanksgiving Day break.

"A student of the district recently took to social media to express their personal opinions on diversity in our nation,” school officials posted on Facebook. “We assure anyone who read those comments that they do not reflect any of the teachings of this school district, nor are they indicative of the beliefs of the staff, administration or Board of Education. The district is seeking the best resolution possible to this matter, and trusts that all concerned understand the Constitutional rights and privacy concerns governed by the Illinois School Student Records Act that must be considered."
