A Thai man was arrested after entering the enclosure of Moo Deng, a popular pygmy hippo at Khao Kheow Open Zoo, AP reported.

The man allegedly climbed into the enclosure while no staff or visitors were nearby and stayed briefly before being caught. Authorities later charged him with trespassing.

Zoo director Narongwit Chodchoy confirmed that Moo Deng and her mother Jona were unharmed, though slightly startled.

Moo Deng rose to global fame after her birth in 2024, attracting large crowds and online attention. Officials say the man has been released on bail, and further investigation is ongoing.
