An active shooter at a Wisconsin middle school forced officials to put area schools in a hard lockdown.

An alert for an active shooter outside a Wisconsin middle school forced the school into a hard lockdown Wednesday. 

"There has been an active shooter at our middle school this morning. The individual did not breach entryway," the Mount Horeb Area School District confirmed on Facebook Wednesday.

In a follow-up post, the district announced "the threat has been neutralized outside of the building. Law-enforcement is circulating throughout the middle school to confirm the safety of all students."

"An initial search of the middle school has not yielded additional suspects. As importantly, we have no reports of individuals being harmed, with the exception of the alleged assailant," the school district wrote. 

Mount Horeb is about 20 miles outside of Madison.

This is a developing story.
