A threatening text message lead Chesapeake Science Point Public Charter School to be placed on lockdown Thursday.
At about 9:20 am, a student received two messages from an unknown sender, indicating something was occurring inside the classroom.
The student alerted the teacher who took the class into the hallway. Principal Dwight Jefferson was then made aware and decided to place the school on lockdown.
Police determined at 10:26 am, the building was safe for students and staff to resume inside activities. This allowed school officials to transition to lockout status, where no one is permitted to enter or exit the building.
At 11:15 am, all normal activities recommenced.
Anne Arundel County Public Schools say they informed parents via phone call, text messaging and email, frequently updating them on the status of the days events.
Investigators haven't yet been able to identify the source of the message. Police however do not believe the threat is credible or poses any danger to students and staff.
