POWAY (CNS) - An unfounded bomb threat forced a two-hour lockdown at Poway High School today.

The security measure went into effect at the Espola Road campus about 10 a.m., after a note making reference to an explosive device was found in a

restroom there, according to sheriff’s officials and the Poway Unified School District.

Students were secured in their classrooms and continued with their studies as deputies swept the grounds and rooms with service dogs, PUSD spokeswoman Jessica Wakefield said.

Shortly after noon, the lockdown was lifted with no hazardous items or materials found, sheriff’s Lt. Jason Vickery said.
