Kyodo News says the death toll from a midday stabbing spree in Tokyo has risen to four. The attack at lunchtime Sunday in the Akihabara district also injured 13 others, paralyzing shoppers with fear. Police said they arrested Tomohiro Kato, 25, on the spot. Local reports said the attacker grunted and roared as he slashed and stabbed at his victims at random on a street crowded with shoppers. The electronics and video game district, known as Electric Town, is wildly popular with Japan's cyber-wise youth.
