Accident due to someone else negligence

I was traveling on my car and I met with an accident with a bike, however I was not at mistake, the mistake was purely of the bike rider as he came to my side of the road while overtaking a car on his side at the blind turn, immediately after the accident I came out of the car and wanted to shout at the bike rider for his negligence in driving, however, after seeing his state and his wounds, I carried him to the nearby civil hospital with the help of passing vechile. His wife thanked me for my cooperation for dropping him to the hospital and accepted that he was at mistake, however after 1 hour when their other relatives reached the hospital , they changed their tone and started asking for compensation of 1.2 lac, further in order to save him I turned my vechile more towards left and which led to damage to the govt electric pole and their staff also started asking for compensation from me of 15 thousands. After hearing all this nonsense I decided to file a FIR against the bike rider to allow the matter to be investigated. Police told me that the bike rider family will also file FIR against me and as their is no witness, I can also be held guilty towards it. Request guidance on the issue, my vechile is fully insured and full documents are available.
