Shivakumar was arrested by the agency late evening on September 3, after which he was sent to the ED's custody for ten days by a Delhi court.
A money laundering case was registered by the agency against him in September last year, based on a complaint filed by the Income Tax Department.
The I-T Department, during the initial probe, had found unaccounted and misreported wealth linked to Shivkumar.
The I-T Department also came across money laundering and hawala operations, involving a network of persons across Delhi and Bengaluru. They had allegedly set up a base in order to transport and utilise the unaccounted cash.
