LUCKNOW, Nov. 4 -- A man arrested for posing as an IRS officer and trying to meet visiting Tripura chief minister Manik Saha at a Lucknow hotel faked a heart attack in an attempt to evade police custody, said officials on Monday. The accused, Prashant Mohan, a resident of Bihar, had been staying at a five-star hotel at Lucknow's Vibhuti Khand since October 30. On October 31, he attempted to meet the CM who was staying on the same floor of the hotel and attended a conference at KGMU, said police. According to officials, Prashant claimed to be an additional commissioner in the ministry of finance and forced his way towards the CM's suite, flashing a fake IRS identity card. As the chief minister's security team became suspicious and denied him access, they alerted the local police. As officers intercepted Prashant while he was checking out of the hotel, he suddenly collapsed and pretended to have a heart attack, leaving police personnel momentarily alarmed. He was rushed to Dr Ram Manohar Lohia Hospital, where doctors confirmed he was in perfect health and had staged the episode to evade arrest. "The police recovered fake IRS and IAS identity cards, visiting cards, Aadhaar and PAN cards, an expensive phone, Rs.1,600 cash and a trolley bag from him," said SHO Amar Singh. Officials also revealed that he arrived in a vehicle fitted with a red-blue beacon light and had a driver. Investigators suspect he frequently posed as a senior bureaucrat to mingle with politicians. Police said Prashant earlier lived in Shakurpur, Delhi, where he taught UPSC aspirants. He had appeared for the civil services examination several times, but failed to clear it....
