New landlord entered my flat without notice in Pune, is this legal?

I recently shifted to a flat in Pune, and the new landlord has entered my flat without any notice twice in the last month. I feel that my privacy is being invaded, and I am quite uncomfortable with this. I have tried talking to him, but he insists it’s his right as he owns the property. Is there any legal recourse for this situation under Indian law? What can I do to protect my rights?
