The Madras High Court Bench here on Monday denied bail to M. Krishnamurthy alias Murthy (56), former PA to Tourism Minister S.P. Shunmuganathan, in a case against him by Thoothukudi Town Police on charges of cheating a couple by promising to get a government job for the woman on payment of Rs.3 lakh. The complainant P. Kirubanantha Murugan, a Dalit, accused the applicant of not getting the job of Lab Assistant in a government school for his wife despite receiving the money. He also alleged that the accused abused him by referring to his caste. Hence, the police had booked the petitioner under the Scheduled Castes and Scheduled Tribes (Prevention of Atrocities) Act also and arrested him on March 16.
