District Collector Siddharth Jain on Wednesday asked Joint Collector T. Baburao Naidu to inquire into complaints over the alleged role of the District Medical and Health Officer in campaigning for the YSRC. The DMHO is reported to have released letters with her signature for circulation within the department asking her staff members to vote for ‘fan’, the YSRC symbol. Mr. Jain took serious view of the complaints and warned the official machinery of punitive action if it was found guilty of working for any party in violation of the Model Code of Conduct.
