REUTERS/Hannah McKayThe Central Bureau of Investigation on Thursday filed a 2,000-page dossier in a London court as evidence against embattled liquor baron Vijay Mallya, who is wanted in India for defaulting on several bank loans amounting to nearly Rs 9,000 crore. Mallya also appeared before the Westminster Magistrates Court for the hearing in his extradition case.The court has set the next date for hearing on September 14.Mallya has been hiding out in a mansion near London since March 2016 and was briefly arrested by Scotland Yard on an extradition warrant on April 18, before being let off on a bail bond worth 650,000 pounds.”I do as my lawyers advise,” the 61-year-old former chief of erstwhile Kingfisher airlines said when asked about his appearance despite being granted an exemption by Chief Magistrate Emma Louise Arbuthnot at the last hearing on June 13.If the District Judge rules in favour of his extradition at the end of the trial, the UK home secretary must order Mallya’s extradition within two months of the appropriate day. However, the case can go through a series of appeals before arriving at a conclusion, said the Times of India, reporting the development on Thursday.The development comes in the wake of a Prevention of Money Laundering Act (PMLA) court on Wednesday issuing a fresh non-bailable arrest warrant (NBW) against Mallya and other accused, including IDBI officials, in the alleged loan default case.On 13 June, Chief Magistrate Emma Louise Arbuthnot had granted bail to Mallya until 4 December and scheduled the next hearing for 6 July. The court had exempted Mallya from being present personally for the hearing.

The ED chargesheet in the PMLA court on Wednesday revealed that Rs 417 crore was remitted outside the country under the pretext of lease rental payment and other miscellaneous payments. Moreover, ED has alleged that the brand valuation of KFA was wrong.The court issued the fresh NBW at ED’s request after the anti-money laundering agency submitted that Mallya is in the UK and has failed to appear before it on previous occasions too.
