Crunchyroll: Man Arrested For Simultaneous Theft Of All 64 "One Piece" Volumes.
Police in Shizuoka apprehended a 26-year-old in Fujieda as the suspected thief of all 64 volumes of One Piece.
Source Yomiuri Online points out that stacking 64 volumes reaches a height of over three feet (1 meter) and weighs nearly 22 pounds (10 kilograms).
You can definitely fit that in a Boston Bag, though, which is what two employees noticed the suspicious-looking fellow carrying the evening of December 23rd. However, the store was busy, so it wasn't until the next morning they noticed the shelf that used to contain One Piece was empty. When they checked the security camera tapes they could see him cram the manga by ten volume handfuls into the bag and then walk calmly out of the store.
