Officers from Harlan police department in Kentucky posted a wanted notice on their Facebook page for Elsa from Disney's animated film Frozen.
"Suspect is a blonde female last seen wearing a long blue dress and is known to burst into song 'Let it Go!'," officers wrote.
"As you can see by the weather she is very dangerous. Do not attempt to apprehend her alone."
A few minutes later, police posted another message saying that, all jokes aside, the weather was dangerously cold and temperatures would continue to fall.
Police didn't say if they'd tell Elsa to "freeze" in the event they found her.
