NEW DELHI: The Enforcement Directorate arrested Congress leader and former Karnataka minister D K Shivakumar on Tuesday for allegedly being evasive during his questioning on money laundering charges over the past few days.Shivakumar was questioned for the last four days since he was summoned for questioning at the ED headquarters here on Friday and his arrest led to Congress protesting that this was more evidence of the government acting out of political motives as in the case of former finance minister P Chidambaram. The leader, seen as a prime political "manager" during the Congress-JD(S) government in Karnataka, had unsuccessfully moved Karnataka HC to seek a stay on the summons by the agency .Sources said he was asked to explain the source of funds he used to acquire properties in Delhi and Karnataka, as well as Rs 10 crore in cash recovered during I-T searches on his premises in 2017.He was also asked about some shell firms and his alleged association with them, sources said. ED officials asked him to disclose the source of Rs 7.5 crore cash recovered from his residence in Delhi's Safdarjung Enclave on August 2, 2017, and Rs 2.5 crore recovered from premises in Bengaluru during I-T searches . Congress accused BJP of vendetta politics."The arrest of Shivakumar is illegal. He is innocent. There is not an iota of evidence against him. This mismanagement and anarchy is only to target Congress leaders," said Congress spokesperson Randeep Surjewala.Shivakumar's premises in Bengaluru and Delhi were searched in August 2017 at a time when he had given shelter to 44 MLAs from Gujarat at his Eagleton Golf Resort on the Bengaluru-Mysuru highway. Congress MLAs from Gujarat were brought to the resort to save them from being poached by BJP on the eve of Rajya Sabha polls in that state where senior party leader Ahmed Patel was one of the candidates .During the I-T searches, officials had also seized a huge stash of jewellery from the residence of Shivakumar's sister-in-law. Sources in the government have alleged that the valuables, in fact, belonged to the Congress leader's wife .The I-T department, which has filed a chargesheet against Shivakumar, has provided "corroborative" evidence to the ED for a money laundering probe against lawmaker. The details of shell firms have come from the I-T department which had earlier said some of his alleged investments in foreign countries were being tracked.
