How to be a Good Samaritan

>This incident happened some time back in Bengaluru: I see a intoxicated guy laying on the side of the road (I do not know who he is, he was shivering very hard though). I pass by on the same road again after few minutes, he is still there but this time I notice some blood near his head and hands. So, I call 112 and they send two police officers. They told me that since I called, I have to accompany this person to the hospital on an ambulance. I was willing to do that. Then they told me I would have to take care of this person after the hospital until any of his family members show up. They implied something along the lines of, if he passes then I would be held responsible in some way. I then pleaded that I was a student in a PG and couldn't do that much. That I just saw someone that needed help and informed 112. After pleading for some minutes, they let me go. This whole incident made me feel unsafe for just being a responsible person. The whole time I was also on the phone with an ambulance. I feel many people don't do the right thing because they are scared of facing this interaction.(At least a 100 people would have walked past this guy. This happened in a very crowded place) I don't want to be scared the next time that I report some incident like this. (I read about some Good Samaritan Rules on the internet, but I am not a lawyer, and would like some clarity on how to handle this type of situation and my rights, that's why I am asking this question)
