Authorities in Mexico responded to the break room of an office building to wrangle an unusual trespasser -- a spider monkey.

Poachers slaughter mother spider monkeys in the wild and then steal their babies, shoving them into boxes, bags and car trunks for a brutal journey to the U.S.-Mexico border.

Wildlife trafficking is one of the world's biggest illegal trades, and the U.S. creates much of the demand for pet primates. Now there's a proposed ban on privately owning and breeding these animals.

The incident underscores the growing demand for exotic pets, as spider monkeys have become one of the most commonly trafficked animals across the U.S.-Mexico border, according to wildlife officials.
