False case threat by a criminal and local police

Hi, I am Adithya, 37, unmarried staying alone male. I live in a shared compound with two other families. The other two families were involved in a honeytrap case(used a random social media profile picture, impersonated as someone else, extorted money from few local people) it was telecasted on local news channels, the SP in media briefing said all the accused have confessed to criminal accusations made against them. I have been an informant in this case. Now these two parties are out on bail and local police does not seem to have filed the charge sheet at all. I went Super intendent of Police requesting him to consider me as an eye witness as I have seen them talking over the phone pretending to be someone else also I have seen them collecting the extorted money. The SP called local police station PSI and advised him to inquire. On my way to meet the local police station PSI who is the IO investigation officer I get a call on my cell phone from one of the ASI from the same station who indirectly threatened me of consequences if I go ahead and become an eye witness in the case I did not meet the PSI and returned home. After returning home I overheard the accused in the case talking to his mother and wife to file a false sexual assault case and get admitted into a government hospital accusing me of assault if in case I proceed with becoming an eyewitness in the case. I am still willing to become an eyewitness but without getting caught in a false police case. The accused are involved in illegal sand mining and the local police are very supportive of them. The honeytrap came into media light is only because the social media profile picture used was of an Indian Army personnel's wife and they persistently followed the case till the criminals were caught but seem to have lost interest in the case after the accused are out on bail. Please guide me to how to go about it.
