Former Karnataka chief minister H D Kumaraswamy on Sunday slammed the Enforcement Directorate (ED) for refusing to allow a plea by senior Congress leader D K Shivakumar for exempting him from appearance before it on Monday in view of Ganesha Chaturthi festival. Kumaraswamy termed as vindictive attitude the EDs action in summoning Shivakumar to appear before it on a festival day. Shivakumar, a former Karnataka Minister, had appeared before the ED in New Delhi on Saturday for the second straight day in the money laundering case filed against him and others. According to him, the ED has asked him to appear again on Monday. Gowri Ganesha is an important festival for Hindus. Mr. @DKShivakumar had asked for a day to observe the festival. However, ED officials denied him even this. If this is not vindictive attitude, then what is? Kumaraswamy tweeted. Shivakumar was a Minister in Kumaraswamy lead Congress-JD(S) coalition government. After a day-long questioning on Saturday, Shivakumar had said ED issued summons seeking his appearance again on Monday, rejecting his request for relaxation as it was a festival day. Speaking to reporters in Delhi on Saturday night, he had said that according to his family traditions, they offer prayers to ancestors like on the day of the festival. We requested stating that I have to offer my respect to elders of the family on the day of the festival. They said no and have issued me summons to appear at 11 am (on Monday) I have happily accepted it, he had said. On Friday, the investigating officer of the case had grilled Shivakumar for over 4 hours and recorded his statement under the Prevention of Money Laundering Act (PMLA). The ED had asked him to appear for questioning after the Karnataka High Court dismissed his plea challenging earlier summons. Karnataka Congress on Friday had defended Shivakumar and accused BJP lead central government of misusing investigating agencies to take revenge against him. Shivakumar and Congress have indicated that his instrumental role in ensuring safe stay of Gujarat Congress MLAs in a Karnataka resort during the Rajya Sabha polls in 2017, amid allegations that the BJP was trying to poach them, was the reason for the I-T searches and subsequent ED action against him. The ED had in September last year registered the money laundering case against Shivakumar, Haumanthaiah, an employee at Karnataka Bhavan in New Delhi, and others. It was based on a charge sheet (prosecution complaint) filed by the Income-Tax Department against Shivakumar last year before a special court in Bengaluru on charges of alleged tax evasion and hawala transactions worth crores. The I-T department has accused Shivakumar and his associate S K Sharma of transporting huge amount of unaccounted cash on a regular basis through hawala channels with help of three other accused.
