Yes it is sad.. But this is a normal practice. Normally employers select a country which grants on arrival visa to most of the countries, instead of visiting each and every country of the applicants.. This is a usual practice and since Nepal grants visa on arrival to Pakistanis, probably he couldn't realize it could be a trap..
Anyway, gone is gone.. Indians couldn't bring him on media as his family already reported his disappearance and media got hold of all the email communication..
I think from now on, Nepal is on the list of countries where we shouldn't go.. Also, India has started a game which has no end.. unfortunately..
