Several big defaulters like Nirav Modi, Mehul Choksi, Vijay Mallya among others have fled the country after taking huge loans. Their passport details were available later.

Last week the Cabinet had approved Fugitive Economic Offenders Bill 2018, which would facilitate action against big defaulters.

Finance Minister Arun Jaitley had said: "Under the Bill all the assets (in the country) of the offender will be confiscated and not only the proceeds of crime. Even benami assets, if any, would be seized."

This Bill also has a provision to confiscate assets of the offender in foreign land as well, for which the government would have to make arrangements with different countries.
