Douglas High School was briefly locked down Friday afternoon after the school's resource officer received an e-mail threat that a shooting would take place on campus, authorities said.
Resource officer Greg Shields, a Douglas County sheriff's deputy assigned to the high school, opened the e-mail at 12:52 p.m. and alerted school and sheriffs officers, the Gardnerville Record-Courier first reported on its Web site.
Deputies kept students in classrooms and closed off the campus in this rural community 15 miles south of Carson City while a search was conducted. The school was reopened an hour later.
"Exactly what the note said, I don't know," said Sheriff's Sgt. Tom Mezzetta. "It made reference that there would be a shooting at school today."
Mezzetta said no weapons were found during a search of the grounds and no shots were fired.
The incident comes one day after a student was injured during a gang-related fight in the school commons.
Investigators don't know if the incidents are related, Mezzetta said.
