UPDATE: Lockdown is over.  See the note from Principal McKain-Fernandez in Scott’s comment below.

A tipster writes in and lets us know that Decatur High School is under lockdown again this morning.

CSD’s Maria Lewis tells DM…

“Yes, DHS is currently on lockdown. The police are searching lockers and the students have been detained inside of their classrooms until the search is complete. For the protection of the student involved, I cannot release any additional information at this time.”
