The case was registered two days back under Sections 124-A (sedition) and 505 (statements conducing to public mischief) of IPC following directions from a local court, said a South Zone police official.
A local court had last week directed police to investigate and file a case against Kavitha, the Nizamabad MP, upon a complaint over alleged remarks attributed to her. The complaint was filed by K Karunasagar, an advocate and the convener of the BJP's city legal cell.
The complainant in the petition alleged that Kavitha, in an interview, had made observations that Jammu and Kashmir and Telangana were not part of India earlier.
The police official said legal opinion is being sought on the matter for further action.
