Two American citizens were arrested in Japan for entering a monkey enclosure at Ichikawa City Zoo, where a baby macaque named Punch gained fame. One man, a 24-year-old college student, climbed a fence, while the other, a 27-year-old singer, filmed the act. They face charges of forcible obstruction of business. Punch became an internet sensation after being photographed with a plush toy, leading to increased zoo visitors and some local discontent over tourist behavior.
