Enforcement Directorate officials today interrogated former union minister Matang Sinh’s aide Khyati Sadannah in connection with the Saradha scam.

ED sources told PTI that she was interrogated to ascertain the details of Sinh’s involvement in the scam by entering into a business transaction with Sudipto Sen, owner of the tainted Saradha Group.

She was interrogated by ED officials for more than 90 minutes.

Sinh is now in CBI custody after his arrest by the investigating agency on January 31, 2015.
