Zebra returned to zoo after Seoul escapade

A zebra that escaped its pen and roamed for hours through the South Korean capital, captivating the internet and sparking thousands of memes, is safely back at the zoo, officials say.

Sero the zebra is back in his pen in a "stable condition, healthy and sound," an official at the Seoul Children's Grand Park said, after the animal spent three hours Thursday trotting along roads and dodging cars before he was finally cornered by park wardens.

Sero, aged 3, was tranquilised and caught using a safety fence after he entered a narrow alleyway, before being returned to the zoo.
