During an investor call, BlackRock questioned HDFC Bank about Atanu Chakraborty citing "ethical" issues while resigning as the bank's part-time chairman, saying, "It's basically a very sketchy remark." When HDFC Bank interim part-time head Keki Mistry said he's "not aware of any issue", BlackRock replied, "[If] you guys have no idea why...how can you say there's nothing behind it?"
