The Securities and Exchange Board of India (Sebi), in March 2012, had slapped the fine on Thanvi for violating securities law in the matter of E Star Infotech.
However, he failed to pay the dues. Sebi, which was recently given powers to recover penalties from defaulters, initiated a recovery proceeding against him.
In a notice to Punjab & Sindh Bank, Sebi has ordered "to attach the locker held by the defaulter either singly or jointly with any other person with your bank".
The direction has been given as Sebi believes that the defaulter may dispose of the assets in the locker and realisation of amount due would in consequence be delayed or obstructed.
