WALKER — After investigating a potential threat to Walker High School, officials said classes were allowed to return to normal operations Friday morning. 

Law enforcement said that they were investigating a potential threat to the campus and, out of an abundance of caution, restricted flow to Walker High's campus. 

"No evidence of a credible threat at the school has been confirmed at this time," officials initially said around 11 a.m. 

Following a search of the campus, an all-clear was given and classes resumed shortly before noon.
