IPC 338 and 279

Dear Sir, Few days before i went to pick one of my friend with my motor cycle . i met with an accident with one old person (76 years) who was trying to cross the road and came in front of the motorcycle. but he was conscious so with local public i took him to the hospital and we contact his family after doctor and police took my statement. and took him for treatment i was there 2-3 hrs. while leaving from hospital i met his wife and gave my number if there is any need they can contact me that time they said they will not launch complaint against me as i had help them. and after few hours i got a call from local police station saying that victims daughter launch complaint against me. so i ran to police station and i explained everything to police and that victims daughter but she was not ready to listen and launched complaint against me. police arrested me and took me in custody and next morning i got bail. after that incident now again his daughter sent me legal notice for compensation of Rs. 7,00,000/- . and in that they mentioned i rode my motor bike negligently and i didn't even asked them and i ran from incident situated place. but that was not true.
