Meh. I have no relation to the university in question, I don't know any names of those involved; the story was told to me by a casual acquaintance some years back, who had heard it from someone else etc. so it's hardly substantive details. If the CIA want to investigate every Iranian who used to be in some undisclosed European university half a decade ago (probably tens of thousands of people, with no central records to tap; said person might just be visiting for some months and not registered anywhere), on the basis of internet hearsay, they can be my guest.
