Japan is investigating reports two of its citizens were detained in Italy after allegedly attempting to take $134 billion worth of U.S. bonds over the border into Switzerland.
Apparently Japanese, but in a case like this I wouldn't trust anything until it has been confirmed.
Potentially, it could be fake securities, but at that scale I doubt it. More likely it's a international criminal group, a major corporation or a government trying to smuggle real ones. It seems likely to me that this is Japan, China or some other country, trying to sell some of it's US Treasury bonds secretly.
