When Ganga Singh Dhillon, 48, a US-based travel agent arrived in the country some weeks ago, customs agents gave no more than a cursory glance at the items in his luggage. If they had examined them more closely, the Government would have been spared a great deal of embarrassment and been better prepared for the macabre events that followed. Dhillon's suitcases contained wads of rather unusual passports, official seals, letter heads, maps and postage stamps of a country nobody had heard of till - then, that is.
