CBI's Economic Offences Wing in Mumbai had registered a case against Acharya who is also the head of Mid-Corporate wing of the Bank, former SBI official K K Kumarah and Chairman of Worlds Window Group Piyoosh Goyal for alleged graft.

Kumarah was arrested in the case yesterday. The agency said that Goyal had allegedly applied for over Rs 400 crore of corporate loan from SBI but only Rs 75 crore was approved.

Kumarah, who had joined Worlds Window Group after leaving SBI as an advisor, allegedly tried to get loans cleared for the company using his contacts in the bank, the agency said.
