State-owned lender SBI on Wednesday approached the Debt Recovery Tribunal and sought the arrest of the ex-chairman of UB group Vijay Mallya, and also the confiscation of his passport, for defaulting on loans. Mallya and Kingfisher Airlines owe ₹7,800 crore to a consortium of 17 lenders led by SBI. Notably, the loan was not serviced since January 2012.
