A person dressed as a ninja broke into an Anchorage, Alaska, comics and games store Friday night and only took one thing—arguably the one thing a ninja needs most: a katana sword. The only damage left behind was at the point of entry, and when staff members reviewed surveillance footage, they saw no evidence he took anything other than the sword, KTVA reports. Anyone with information on the burglary is being asked to email the store, Bosco's, or call Anchorage police. (More weird crimes stories.)
