Japanese authorities have taken two American citizens into custody following a bizarre stunt at Ichikawa City Zoo. On Sunday morning, a man who identified himself as a 24‑year‑old college student climbed over a fence and entered the enclosure of Punch, the nine‑month‑old macaque that has become an internet sensation after being seen cuddling a plush orangutan. A second individual, claiming to be a 27‑year‑old singer, filmed the incident while wearing a costume promoting a cryptocurrency.

Security footage released by the zoo shows the costumed figure leaping into the enclosure with the stuffed toy, after which a zookeeper quickly intervened and escorted him out. No animals were harmed, and both suspects have denied any wrongdoing. Police have charged them with forcible obstruction of business, a violation that carries significant penalties.

Ichikawa City Zoo issued a statement confirming that it has filed a damage report and is implementing new safety measures, including expanding the viewing restriction zone and installing intrusion‑prevention nets. The zoo is also reviewing its policy on filming near the monkey exhibit and has temporarily halted requests from YouTubers and other content creators.

Punch, who was abandoned by his mother earlier this year, first captured public attention when keepers gave him a soft‑toy orangutan for comfort. Since then, the zoo has regularly posted updates showing the macaque bonding with his peers, often seen playing with or being embraced by the toy. The recent trespassing incident adds to a growing list of visitors attempting to breach zoo barriers after animals achieve viral fame, highlighting the challenges institutions face in balancing public interest with animal safety.
