Liberty High School announced Thursday that it will be closed on Friday, April 21 due to a potential threat.

Liberty High School Principal Sean Martin said that because the credibility of the anonymous threat could not be verified, it was best to take precautions and close school for the day.

“While the closure of school tomorrow is disruptive, we believe it is in the best interest of student and staff safety and will give law enforcement the opportunity to investigate the situation further,” he said in an email sent out to parents.

The King County Sheriff’s Office is currently investigating the threat.
