The Flagstaff Police Department said the Fort Valley Road sign was reported at about 3 a.m. Monday and Arizona Department of Transportation officials said it had been returned to its usual message about left turns not being allowed at the upcoming intersection by 11 a.m. Monday, the (Flagstaff) Arizona Daily Sun reported Wednesday.
"We want to assure all citizens of Flagstaff that there is no problem with rogue pandas," police Lt. Ken Koch said.
Mackenzie Nuno, a spokeswoman for ADOT, said the hacker would have needed specialized equipment to change the sign. She said investigators do not currently have any suspects.
