A U.S. school says a missing Mickey Mouse spurred a brief lockdown while parents were visiting the school for Valentine's Day parties.

The Vindicator newspaper in Ohio reports a parent wanted to surprise a class dressed as Mickey Mouse but failed to tell the principal. The woman signed in at the office, then changed into the costume in a restroom. She changed out of the costume after leaving the class.

Superintendent Dante Zambrini says "it was a case of, Mickey Mouse was here, and then he was missing." The school was locked down as a precaution.

The superintendent says the woman talked with police and they determined she didn't mean any harm.
