Keeping security of info in view, i can only tell that he was abducted ofcourse, but the way it was done and the precedent it has now set, both have put Indian agencies in a fix. Warnings from our side have already gone out, when this incident happened, that if they want to adopt this way, then all their officers abroad (on courses, in embassies, and other covert/overt assignments) will be picked off as well.
Indians cowered down and are now willing to return the Colonel (without Kalbushan in exchange). But now they cant find a proper and respectful way to return him....
