Sahar Sheikh, an AIMIM corporator from Mumbra's Ward No. 30 in Thane, Maharashtra, is embroiled in controversy following an inquiry into her caste certificate. The Thane tehsildar's office, led by Tehsildar Umesh Patil, has recommended filing a First Information Report (FIR) against her father, Yunus Sheikh, after discovering that the family allegedly used a fake Other Backward Classes (OBC) certificate during the January 2026 Thane Municipal Corporation elections. The inquiry was initiated after Siddiqui Ahmad, whose daughter lost to Sheikh, raised concerns about the legitimacy of her caste certificate. The investigation revealed that the certificate, issued in 2011, did not adhere to the official Maharashtra format and lacked necessary signatures. Furthermore, the Sheikh family's origins in Ghaziabad, Uttar Pradesh, raised questions about their eligibility under state rules. They reportedly applied using Form 8, intended for native residents, instead of the required Form 10 for migrants. The inquiry also scrutinized the issuance of the certificate from the Mumbai city collector's office, suggesting an attempt to evade local verification. The tehsildar has advised the cancellation of all related caste certificates and has forwarded the report for further legal action.
