Child abuse in government school.

Hello people of Mysore, I am 25 years old masters student who has to do 7 days program with a NGO. I noticed that school uses beating as a punishment, many students mentioned to me that they are beaten for minor things. Even little girls aren't spared, male teachers mercilessly beat girls without any regard for the boundaries and safety. The girls and boys complain about pain, swelling to the point they can't move there hand. I want to stop this but my complaints have been futile till now. Please, inform necessary authorities as I'm not from Mysore. NGO: Kalisu Foundation. School Name: GHPS Kumbarakoppal.
