Ryan International School — Principal's behaviour

Address:

Mumbai City, Maharashtra, 400706

My brother studies in 9th class in ryan international school sanpada navi mumbai.
recently my father was complained about my brother's behaviour.
complaint was that my brother was part of group hitting a boy of 9th.
that day he was just given a warning.
after 9-10 days as farewell was completed, my brother with his friends were made to stand for about 4.30-5 hours with no break, and all got suspended for 3 days.
reason for suspension after so many days can be that there were less students to dance in farewell.
and moreover.. principal was misbehaving with parents. she was shouting at parents and was showing off her post.
she even said "bring whomever you want police or anyone.."
she was threating my parents.
such a attitude is not good as a principal of school.
