Is it something that can be dangerous for me?

I m(26) from Delhi. I teach at an institute. I had an argument with one of my student due to our misunderstanding. I gave her some work and she did complete opposite thing and when i pointed out, i may have touched her nerves or something and she(25) got furious. The next day (13th jan 2025) she called her brother to institute, he literally abused and had heated argument, my management apologised for things that hadn't been committed. On 20th jan we refunded her fees. After that the brother and the sister went to police and cops came I was not there at that time and my institute head handled everything. When i reached i got to know the duo wanted a begging apology from my side and i called back the police he said we will let you know.

Now comes the real thing. I got a call at 11:12, saying he is SHO and wanted all my complete details like address, i politely refused as i had suspicision and felt intimidated. I told i will give every detail in station. He cut the call saying come to station tomorrow.

At this point i dont know what to do. Can someone please guide me.

UPDATE:-

The guy who called last night by pretending to be SHO or he may be real one, again called at 11am.

I didnt pickup the call and now i talked to my institute owner who said that he has called police station and case has been closed last night only.

So either the call guy (if he is SHO) wants money from me or the brother of that girl is calling pretending to be SHO to get my address.
