IPad pro 9.7 screeching noise (Please Help)

I brought an iPad pro 9.7 inch two days ago. Yesterday when I was using Facebook messenger (about to type a message) there came a very loud bang sound from the top of the ipad ( as if sth has exploded inside at the top).......and then it started making a loud screeching noise...i dropped my iPad on my bed and went to my parents....then my bro came inside the room n switched off the ipad then when he switched on the ipad again...he said it was working n it didn't make any noise since yesterday....i have not used my iPad pro since then.....PLEASE HELP......should I start using again?will it happen again? I am scared coz there came a loud bang from inside on top......PLEASE TELL ME WHAT'S WRONG
