Pet zebra on the run in Tennessee after escaping and "wreaking havoc" on highway

A pet zebra has been on the run for days in Tennessee after "wreaking havoc" on a highway outside of Nashville, officials say. 

"Several professional tracking groups are involved in the search and a K9 search is scheduled Tuesday," the Rutherford County Sheriff's Office said in an update Monday on social media. 

The zebra escaped into a wooded area off Interstate 24 on Saturday afternoon, the sheriff's office said. The animal had been running through traffic on both sides of the highway, forcing a temporary closure.
