Four cubs and an adult lion escaped from their enclosure at Sydney Zoo, Australia. The zoo was immediately put into lockdown with staff and visitors moved to safe zones. Fortunately the lions returned to their enclosure without any injury.

The good thing is that no one got hurt with this incident. If I were a zookeeper, I would be scared to death not only for me but also the innocent souls there.
