Suspicious Submarine in New York Harbor!

This morning police spotted three (relatively) young men boarding a strange vessel in New York Harbor. Upon closer inspection, the "boat" in question turned out to be a homemade submarine. (See more pictures here and a video here.)

Apparently, the underwater craft was modeled after the "Bushnell Turtle," the first American submarine, which was invented in 1775. No one seems to know why the men built the submarine or what exactly they planned to do with it. All three were arrested--not because they intended to do any harm--but because they were too close the luxury cruise ship, The Queen Mary II. More information to come!

UPDATE AUGUST 4: The New York Times has a wonderful video of Duke Riley, the artist behind the sub, explaining his motives. You also get to see his creation up-close. I have to say, I'm really impressed! I wouldn't mind having a submarine of my own.
