Police were tipped off that strange animals were seen walking around the streets. The escapees consisted of fifteen camels, two zebras a few lamas and a number of pot-bellied pigs.

It's thought that a giraffe kicked their enclosure open. The circus' staff and police were able to round up the animals relatively quickly.

WARNING: The Attached Animal Training Video Is Very Graphic

Animal trainng cruelty is an issue with circuses. Circuses.com says "The fact is, animals do not naturally ride bicycles, stand on their heads, balance on balls, or jump through rings of fire. To force them to perform these confusing and physically uncomfortable tricks, trainers use whips, tight collars, muzzles, electric prods, bullhooks, and other painful tools of the trade."
