Overreaction at the Bus in South Korea

Well, I got this from another website, this is what it said, don't blame me if the story isn't 100% true

Apparently, the woman said something in Korean, I believe the word is NIGA, and it sounds like nigger or neger, and then this happens...

Does anyone here know Korean and can confirm that they have a word that sounds like this?
