Officials in a school district in Pennsylvania decided to cancel classes for Friday after an alleged threat was found at a high school.

The Greater Latrobe School District announced that a note was found in a bathroom at Greater Latrobe Senior High School, school officials said.

The note was scribbled on a bathroom wall and mentioned Friday's date.

School leaders do not think it's credible, but are canceling classes at all five schools in the district as a precaution.
