An interstate has been closed. A drone has been deployed. Professional tracking groups and trained dogs have been dispatched.

They’re all on the case of a missing zebra that has been running wild for nearly a week in Rutherford County, Tenn., eluding efforts to recapture it.

The latest sighting was on Friday, when sheriff’s deputies tracking the startled zebra with a drone spotted it trotting through a field near Christiana, a community about 40 miles south of Nashville, prompting them to urge people to avoid the area.

“We don’t want to scare the zebra,” Cpl. Sean White of the Rutherford County Sheriff’s Office said in a statement. “We need time to get him to calm down.”

Whoever owns the zebra — the person’s name has not been released — only had the animal for less than a day, having “obtained” it on the night of May 30 before it escaped the next morning, the sheriff’s office said.

Lisa Marchesoni, a spokeswoman for the sheriff’s office, said it was not clear how the zebra got loose or why the man owned it, but dispatchers received a call on the morning of May 31 that the zebra was running though traffic on Interstate 24.
