CHIBA, Japan - Two U.S. nationals were fined 300,000 yen ($1,876) each on Friday over a trespassing incident at the enclosure of Punch, a Japanese macaque that went viral for clinging to an orangutan plushie at a zoo near Tokyo.

According to the Chiba District Public Prosecutors Office, the two men were summarily indicted Friday for obstructing the zoo's business, a process that allows prosecutors to seek fines through summary court orders without a formal trial. The men paid the fines, the office said.
