Officials of the Directorate of Enforcement (ED) on Monday questioned former MP, D.K. Suresh, in a money laundering case against city-based businesswoman Aishwarya Gowda, who had cheated several people on the pretext of gold business ventures posing as sister of Mr. Suresh.

Aishwarya Gowda is alleged to have used the name of Mr. Suresh, who is the brother of Deputy Chief Minister D.K. Shivakumar, to cheat several jewellers to the tune of ₹8 crore. She was arrested by the ED in April.
