A fight breaks out between three or four male students aged 15 -17 years on the campus of a private school during the lunch break. The fight attracts a great deal of attention from other students who huddle around the group of fighting boys. The fight continues for approximately five minutes. During the fight, one of the boys is kicked repeatedly in the head and is brain damaged. Approximately 90% of the school's student body is made up of minors. During the lunch break, there are approximately 200 students on campus. The school does not have any staff on duty during the lunch break. Discuss if there is any duty of care and if there is any breach of the duty.
