Mumbai: The British Virgin Islands (BVI) has denied the Income Tax (I-T) Department certain account information, saying it has been destroyed in a natural calamity, sources in know told ET. The information pertains to the investigation into Deepak Kochhar , husband of former ICICI Bank chief executive Chanda Kochhar , in the quid pro quo case.In a related development, the Enforcement Directorate (ED) — probing the Kochhars and Videocon chairman Venugopal Dhoot of money-laundering — has for the first time sought details on the Videocon loan, role of the sanctioning committee and procedures followed, about a fortnight ago.The I-T department had sent Letters Rogatory (LRs) to Mauritius, Singapore and BVI. Singapore has already replied to the queries while a reply from Mauritius is awaited, the sources said. “This is not the first time BVI has cited natural calamity as the reason behind failing to share information,” said an official who spoke to ET on condition of anonymity.“Monies have been moved and received from NuPower Renewable le (Kochhar’s company) to various foreign accounts. In order to check the veracity and the purpose of these funds, we had written to the three countries. BVI replied saying they suffered a natural calamity in which all documents and storage devices have been washed away and therefore, information of the accounts sought by us cannot be parted with,” the official added. “The information given by Singapore has provided certain workable leads. We are also awaiting a response from Mauritius but aren’t hopeful that they will share it.”“Our probe has concluded that the (Kochhars’) flat in the tony CCI Chambers in south Mumbai has been bought through a web of suspicious transactions through companies linked to Videocon group,” said the official.Meanwhile, ED is also planning to write to BVI, Mauritius and Singapore, though inside sources told ET they don’t expect a positive response from the first two.“These countries are tax havens and they are averse to sharing information. We need to get details on the foreign accounts connected to NRL so as to unearth the money trail and connect both the source and the receiver in the chain,” said an official.“The probe has so far revealed that on September 7, 2009, a rupee term loan of `300 crore was transferred to Videocon International Electronics by ICICI Bank and the very next day, Dhoot transferred `64 crore to NRL, managed by Deepak Kochhar. During questioning, Chanda Kochhar has maintained the loan was approved by the sanctioning committee. Details sought from the bank will help us tie up our case that Chanda alone was the beneficiary of loan sanctioned to Videocon,” said the official.Email sent to ICICI Bank on Monday failed to elicit a response.
