The entire article is worth reading.
See post 12, there is a second confirmation of the second arrest. And, reading the article, FBI confirms that they are “holding” indefinitely the second individual “for immigration reasons”. So the bomb dog got him, and they are holding him. But its about his visa.
So we have, apparently, three people on the plane. The bomber we know about, the guy who filmed him, and the guy being “held” that the bomb dog sniffed out.
And the guy at Schiphol who apparently walked the bomber onto the plane.
Weird. Interesting, but weird.
Interesting indeed
