Central Board Of Secondary Education [CBSE] — I am complaining about a teacher

Address:

781035

I am anew student of a school name SBOA public school in gorchuk, Guwahati, Assam. I have passed my examination and have taken admission in this school. Today on this day that is 13th of June 2019 my maths teacher had several beaten me due to unnecessary reasons . It all started when he was roaming in the class to check if everyone had bought their maths book or not . I had brought it and had kept it on the desk and the teacher had told to write something from it . As I was writing he came to me and saw I had only half completed so he drove me out of the classroom and tore the page of my copy . Then he told me to hold my ears. When I was doing so I realised my pen was in my hand, and when I went to put it back into my pocket he got angry and said I am not listening to him and making fun of him and he started beating me in my left hand. I told him that I had pain in my left arm but he didn't stop and was continuous beating me. So now I have a paining in my left arm asa I had gone an minor surgery in my left arm few days ago. This is the teacher of the CBSE board bearing a student from other board like this?
