Delhi Transport Corporation [DTC] — Wrong fine on bus

I was travelling by a bus no. 4717 on route no. 523A on date 24/4/2023 at 4pm three dtc ticket checkers said that show me your ticket I showed then my ticket they said come with us outside the bus. I gone and the slapped me there and teared my bus ticket and said give us fine of rs. 2000 and gave me a receipt of Rs. 200 written on it.
They abused me also.
