In a bizarre chase for zoo officials, a spider monkey not only escaped from a Mexico City zoo but also boarded a bus. If this was not enough for his antics, the monkey also attacked a passenger during its ride.

According to Red Cross officials, the monkey boarded the bus at about 11 pm Monday after escaping from the San Juan de Aragon Zoo. It then sat next to the bus driver for almost an hour as he drove through the city.

However, when a 20-year-old woman tried to hold him, it scratched and bit her. According to Mexican news agencies, the woman was treated for the injuries the monkey inflicted and the animal was placed in quarantine.
