While the Enforcement Directorate questioned Manish Sisodia at Delhi's Tihar jail, the agency also arrested Hyderabad-based businessman Arun Ramchandra Pillai, a close aide of BRS leader K Kavitha. CBI that is also probing the case, has said that Arun Pillai had the role of collecting money from Sameer Mahendru and passing it on to other participants of the scam. With Pillai's arrest, the case has moved closer to BRS leader K Kavitha, who has been accused of holding some stake in IndoSpritis that was a beneficiary of the scam.
