Chauhan was arrested by Enforcement Directorate on July 9 last year in a separate money laundering case related to the present case.
The matter was transferred by the Supreme Court to the Delhi High Court, which on April 6, 2016 had asked the CBI not to arrest Singh and directed him to join the probe.
