phone call from delhi police station asking to appear

I am a Hindu. I think I got fake call from delhi police. I received a call from someone claiming to be from 'delhi police' and told that my wife has filed case against me and my parents. He told me to present myself in ranibagh police station, new delhi - CAW unit after two weeks. I told him to talk to me on phone or virtual zoom call but he said my physical presence is needed and I should come alone. He told me date and time and cut the phone. My wife, kid and family are not talking to me and threatening about court case only. My wife is staying away for 1.5 years. I do not stay in Delhi and stay in Chandigarh. I have not got any details about the case from the 'policeman' and could be mischievous call. I also don't find it appropriate to go without a written notice explaining contents of complaint and reasons for my physical presence. It seems highly unprofessional, unfair and negligent on policeman's part to give me short notice like this assuming the policeman is genuine. What are my legal options? Thank you.
