NEW DELHI: A Delhi court on Friday extended the ED custody of Karnataka Congress leader D K Shivakumar till September 17.Special judge Ajay Kumar Kuhar extended Shivakumar's custodial interrogation after the Enforcement Directorate sought 5-day extension of his custody.Shivakumar, arrested on September 3 by the ED in a money laundering case, was produced before a Delhi court on the expiry of his 9-day custodial interrogation.The probe agency told the court that Shivakumar, 57, was evasive and gave irrelevant answers during the interrogation, and many of his properties are 'benami'."As per the probe against Shivakumar, tainted money is more than Rs 200 crore and there is Rs 800 crore worth 'benami' property," said Additional Solicitor General K M Natraj, representing the ED.The ED needs to confront him with voluminous documents it has collected so far in the case, he said and claimed that Shivakumar was withholding information which was solely in his knowledge.To this, the judge said, "I am sure he won't answer questions in the next five days either. Why do you need his custody".The ASG replied that there are statements by some other accused and Shivakumar needs to be confronted with them.Strongly opposing extension of Shivakumar's custody, his lawyer AM Singhvi told the court that the Congress leader must be in hospital as his condition is very serious.Shivakumar has been in custody since September 3 and today is the 10th day, the counsel said, adding that he must be given active medical assistance."Just because there is power to give remand for 15 days, does not mean that it should be granted," the counsel contended while opposing agency's plea seeking further custodial interrogation."I am a law-abiding citizen," Shivakumar's counsel told the court, which said he will get the best hospital facilities whenever he wants."You have the right to not file a reply but you can't claim automatic remand," Singhvi told court.He further said that Shivakumar's 22-year-old daughter Aishwarya was also interrogated by the ED."I have nothing to hide. If you want to interrogate me, you can call me for interrogation anytime," he told court.However, the court accepted ED's plea and extended Shivakumar's custody by another 5 days. The court also directed the ED to file its response on Shivakumar's bail plea by September 16.Meanwhile, Shivakumar's daughter Aishwarya had appeared before the ED on Thursday in connection with its money-laundering probe against him, the ED officials had said.The 22-year-old management graduate was questioned and her statement was recorded under PMLA.According to the sources, she was also confronted with documents and statements made by Shivakumar with regard to a trip to Singapore he made with her in 2017.Aishwarya is a trustee in an education trust floated by her father.
