Raninder had earlier said he did not have anything to hide and was willing to cooperate in the matter.
The case came to light when the Income Tax department received information about Raninder allegedly holding the offshore account in the alpine nation as part of details received in this regard by the Central Board of Direct Taxes from their French counterparts in 2011.
Both Raninder and his father Amarinder Singh, a Lok Sabha Member, have denied any wrongdoing and termed as "false" the charges.
