Fake threatening calls from Delhi High Court/Sub Inspector

Got three calls from this number (8512096225) saying that he was a sub inspector calling from Delhi High Court and there was some complaint against my father’s name. He mentioned my name and my father’s name with his initials but not the correct name. Then he wanted details of my father. I refused saying that you are not naming him right. To which he responded by telling me my details like location etc. and threatened me to speak up the truth or else he will catch me and used harsh language. When I tried to inquire what it was all about, he said he doesn’t have time to go into the details. Later he again threatened me to tell if I know this person or not who he said was my father. I said NO. I told him you are taking his name with correct initials but the actual name is wrong. (And incidentally one of my uncles’ name has the same name when he uses the initial letters, and the actual name he mentioned was the same as my uncle’s, but that was just a co-incidence to me.) According to him there was some complaint regarding ”chori chakari” for which my father was a guarantor to somebody. He asked me that doesn’t he live in Lucknow? I have no connection with Lucknow and I told him the same. To which he said ”theek hai” and disconnected the call.
