Update at 9:30 a.m. — The school and the aquatic center have reopened after getting the “all clear” from police.
An unspecified threat at Washington-Lee High School has prompted officials to cancel all after-school activities at the high school, including adult education classes. The W-L aquatic center has also been closed.
Administrators learned of the threat this afternoon, school officials said in an email. Police investigated and determined that there was no imminent danger to students and staff.
The building was closed at 3:00 p.m., immediately after classes ended. Police are now conducting a more thorough search of the building.
Arlington Public Schools will announce whether there will be any further cancellations early tomorrow morning. The W-L aquatics center will open at 6:30 a.m., at the earliest, the school system said.
