Bullying seems to take place in all sorts of schoolS - BULLYING

In general, bullying seems to take place in all sorts of school, not just one particular. It may not be restricted by race, color, age or other natural distinctions. Throughout, these cases there are three main roles within bullying: the bully, the victim, and the spectators. According to new york daily news "aided by peers' diversion, bully attacks Denver middle school student as spectators film incident, cheer on attacker: "GET HER!'" it was stated in the article that "On March 8, a 14-year-old girl was aggressively attacked by another 14-year-old girl in the classroom of Denver's Henry World School as some students took video on their phone." As you could see spectators are involved in this manner. Instead of the spectators trying to get the bully to stop what she was doing to the victim, they were cheering her on like it was the right thing to do. After the victim was in that situation it was also stated that 'I felt like I didn't want to live anymore.' "I turned around because I didn't want to fight her, and she grabbed me by my hair," said the victim whom was bullied at Henry World School. The victim was clearly in a pool all alone according to New York daily news "this attack had clearly been planned. Dozens of students created a diversion in the hallway to distract the teacher. The attacker then came in along with a group of other students and started bashing the victim. In the raw video, spectators can be heard cheering on the attacker, with some yelling, "Get her!" It was so messed up the victim parent knew about the incident from another parent that was outside of school. Unfortunately, she could not stop the issue in time according to New York daily news the mother of the victim said in an interview with KDVR that she heard about the incident from another parent instead of the school. The victim said she asked teachers for help multiple times. But "They treated this situation like every other situation they see, and it was not the same," the victim's mom said.

Whatever the case of bullying, there are three major roles that take part in this activity; the bully, the victim and the spectators.
First it is not clear to me what your intention of writing. Is it that you want to analyse these different roles? However, I like if you elaborated a bit more on these three roles before coming to those examples as I feel they come too fast and it is difficult for the reader to understand your motive of writing.
