Mexican police were called to help with an unusual situation early on Thursday morning in Tlajomulco de Zunigaa in the state of Jalisco, when a hippopotamus was seen wandering aimlessly through the streets.
A man who said he kept the animal at his home was not too far away.
The man told police the animal wandered off into the streets when he let it out of its cage for a walk in the park.
After some coaxing, police surrounded the hippo and guided it into a cage. Officers then arrested the man, who didn't have the documentation to prove he was the owner.
