Sikder Insurance Company Limited has invested most of its assets in the capital market, parking funds in a single stock of scandal-ridden National Bank Ltd (NBL), in a corporate wrongdoing influenced by family ties.

Rick Haque Sikder, a director of National Bank Ltd (NBL) and chairman of R&R Aviation Ltd, has defaulted on repayments of a loan with AB Bank Ltd, which might cost him the directorship if dues are not cleared in two months.
