The News Minute | March 21, 2015 | 07.09 pm ISTEven as protests over investigations in the death of IAS officer DK Ravi continue, political parties in Tamil Nadu including the DMK, AAP and others have woken up and begun protests over the alleged suicide of an agricultural engineer in the state. Their ire is targeted against the ruling AIADMK government and a protest demanding a CBI enquiry into the death of S Muthukumarasamy, who had allegedly committed suicide over pressure from then agriculture minister SS Krishnamoorthy. Even though "Agri" Krishnamoorthy was removed by AIADMK chief J Jayalaltihaa amidst other party expulsions, a clear reason for his removal was not cited.According to allegations, the minister was dropped from the cabinet over his role in the death of S Muthukumarasamy, a 58-year-old senior engineer working with the state’s Agriculture department .Muthukumarasamy had reportedly committed suicide by stepping in front of a speeding train in Tirunelveli in February.Said to be an honest officer working with the government, it was believed that sacked minister along with his colleagues had pressurised him to recruit some persons for the post of driver on their recommendations - an idea that did not appeal to the man known for his integrity.More allegations have been floating about the minister’s role in threatening Muthukumarasamy that he would be suspended before his retirement which was approaching this year.SS Krishnamoorthy of the AIADMKA case similar to the one involving poor investigations into DK Ravi’s death, that of an honest officer poking around high places has received wide-spread criticism; similarly, the apparent suicide of Muthukumaraswamy has been gaining attention across the state.As criticism for the lack of a proper investigation into the incident gained momentum, the Aam Aadmi Party’s Tamil Nadu unit staged a surprise protest inside the Tamil Nadu Chief Minister’s residence - a move that is said to have caught the police by surprise.The Aam Aadmi Party who protested by entering into Chief Minister O Panneerselvam's residence in Chennai say that the latest decision to move investigation into the engineer’s death from the railway department to the CB-CID was not quite sufficient.Demanding an enquiry by an independent body, Chandramohan , an AAP committee member said,“We are going to lose the few honest officers if something is not done,” he said explaining that the trend of threatening honest officers was not something new. What should be done? “Removing the minister is not the solution. This has become a fashion..They should be put behind bars” he said. Former Minister Krishnamoorthy has been sacked and reinstated in the AIADMK twice in the past.DMK chief Karunanidhi’s daughter and MP Kanimozhi also visited Muthukumaraswamy’s family and extended her support to them. Earlier last week, cadres of the Communist Party of India staged a demonstration demanding a CBI probe into the matter. AAP members who protested on Saturday inside the Chief Minister’s residence were taken to a hall after the protest by the police pending investigation. TweetFollow @thenewsminute
