NEW DELHI, March 9 (Reuters): Liquor baron Vijay Mallya, under pressure from banks to repay more than $1 billion of debt owed by his collapsed airline, left the country last week, a lawyer for the lenders told the Supreme Court. More than a dozen state-run banks - led by the country’s largest, State Bank of India, - had appealed to the Supreme Court asking that Mallya be stopped from leaving as they step up pressure on the one-time billionaire. On Wednesday, Attorney General Mukul Rohatgi, representing the banks, told the Supreme Court he had been told by police that Mallya left India on March 2, and asked the court to demand his return. Mallya’s exact whereabouts are not known. The court has asked Mallya to reply to a notice issued to him within two weeks, after which it will hear the case again. Details of the notice were not made public.
