A substitute teacher in Louisiana is arrested after authorities allege she triggered false active-shooter alerts at five schools. Sheriff’s officials say Lytonja Barfield used the Caddo Parish School Board’s emergency notification system to send the alerts to multiple campuses.

Authorities describe the incident as involving “false” active-shooter warnings sent through the district’s system. Fox News and the New York Post both report the arrest and link it to alerts sent to five schools in the Caddo Parish area, citing the sheriff’s office. The two outlets also identify Barfield as the person taken into custody and note her age, 58, in their reporting.

Across the sources, the core details align: Barfield is accused of using the school board’s emergency system to issue the alerts, and she faces arrest following the alleged actions. The available excerpts do not add differing accounts about motives or the sequence of events beyond the allegation that the alerts were triggered across five schools.
