The market regulator, which is supposed to protect investors from unscrupulous activities, seems to be falling prey to the same. Last week, a senior Securities and Exchange Board of India (Sebi) official was robbed of Rs 40,000 as he gave away his debit card details to a telecaller who claimed to work for a top public sector bank and threatened that if he did not provide the details immediately his account could be deactivated. And a few days earlier, another Sebi official lost Rs 10,000 in a similar fashion.
