Some as*hole bumped my mother on scooter and fled away, what should be our further course of action?

नमस्कार Today afternoon my mother was returning home when some idiot on a bike bumped my mother and fled away. My mother gave a proper right signal and was turning when the moron on bike, going full speed struck the scooter from right and my mom and the scooter went sliding. He stopped and had the audacity to say to my mother that “ब्रेक नाही आहे गाडी ला माझ्या मॅडम”. He then fled away and struck someone else further, and then fled again. Fortunately, my mom is unhurt with a few scratches but she is shook a bit. Thanks to the helmet, she didn’t struck her head on anything. A kind stranger helped her and noted down the number of the offender. We called police and they have asked us to come to police station. Fortunately we never had to experience this, but what should our family do further legally? What are the formalities of the complaints and how can we recover the damages from him? Any help will be appreciated.
