A teenager is in the hospital with life-threatening injuries after a stabbing at West Potomac High School in Alexandria, according to Fairfax County police in Virginia.

Officers responded to the school earlier Wednesday and found the teen victim suffering from serious stab wounds.

Emergency crews transported the victim to a nearby hospital, where they are being treated.

Police say a teenage male suspect is in custody. It’s unclear what led to the attack, but investigators remain on scene and are working to determine the circumstances behind the stabbing.

Authorities have not released the names of either teen, and it’s not yet known whether the victim and suspect knew each other or if the incident was random.

The school was placed under a brief lockdown during the response, which has since been lifted. Parents were notified through the school’s alert system, and classes have resumed under heightened security.
