BHOPAL: A mob assaulted Ashish Chaturvedi , the whistleblower in India’s largest medical examination and recruitment scam in Madhya Pradesh, in Gwalior on Friday for “teasing girls”.Chaturvedi had exposed those close to Madhya Pradesh chief minister Shivraj Singh Chouhan and seven others for their role in the Madhya Pradesh Professional Examination Board (MPPEB) scam.He was surrounded near Gwalior’s Dal Bazar area and brutally thrashed. Chaturvedi was injured even as his personal security officer (PSO) stood there as a mute spectator.Chaturvedi lodged a complaint and police officers swung into action after additional director general Sudhir Sahi, who is heading the MPPEB scam probe, rang up to inquire about the incident.“There was open threat to my life and I had been complaining about this to Gwalior police. When I was being beaten up, my security guard did nothing," said Chaturvedi.“One PSO cannot ensure my security as people I exposed are close to top politicians of the ruling party."He had earlier made a written complaint to police, citing threat to his life from 30 people booked in the scam.Chaturvedi’s complaint forced special investigation team, investigating the scam, to lodge FIRs against eight people, including former minister Sheetla Sahai’s son-in-law.He had petitioned the CBI to probe admissions of 5,000 medical students from 2003-2013 to all colleges in the state.
