Sero the zebra breaks free from a zoo and runs through the streets of Seoul

After Sero was reported missing from the zoo around 3 p.m. local time (2 a.m. Thursday ET), zoo officials, firefighters and police officers began a wild chase across the busy streets of the densely populated city of about 10 million people.

The zebra was eventually cornered and felled by a tranquilizer dart, after which he was brought home safely around 6 p.m. There were no immediate reports of injuries or damage to property.
