PATNA, April 22 -- An internal fact-finding committee set up to investigate alleged irregularities in the undergraduate MBBS examinations at Indira Gandhi Institute of Medical Sciences has missed its April 14 deadline and is yet to submit its report, officials said. The panel has sought additional time and is expected to present its findings by end of the week. The four-member committee, headed by dean (academics), Dr Om Kumar, includes deputy director (administration) Dr Bibhuti Prassan Sinha, registrar Dr Sarvesh Kumar Singh, and chief administrative officer Praful Ranjan. According to officials familiar with the matter, the panel is examining multiple aspects of the allegations. "We are exploring all angles and the inquiry is continuing. It will be premature to comment at this stage," said Dr Sinha, who declined to share further details citing the probe's sensitivity. Sources said that the committee has come across circumstantial evidence suggesting a possible question paper leak and tampering with students' answer sheets. The panel has recorded written statements from examination cell officials and is cross-verifying them with available evidence. Several staff members, including the primary accused named in the complaint, have been transferred out of the examination cell. However, the probe has been complicated by limited surveillance coverage. Key areas of the examination cell reportedly fall within CCTV "shadow zones," and footage from available cameras is yet to be fully examined. Officials noted that comprehensive CCTV coverage remains lacking in parts of the institute, despite being mandated by the National Medical Commission. In a parallel development, the institute constituted a separate three-member committee on April 10 to examine media reports following the emergence of the allegations. This panel is headed by Dr Sanjay Kumar. Notably, the second committee was formed without disbanding the original panel, which was already nearing completion of its inquiry. Both committees were given a one-week deadline, but neither submitted its report. The exclusion of IGIMS medical college principal Dr Ranjit Guha from both panels has also raised eyebrows. The investigation stems from an anonymous email complaint sent on March 11 to senior IGIMS officials and the undergraduate Medical Assessment and Rating Board (MARB) of the National Medical Commission. It alleged a racket involving an outsourced non-academic staff member and others, who were purportedly facilitating answer sheet manipulation for money....
