WESTMINSTER, Colo. (AP) -- Classes were canceled and students at Westminster High School were searched for weapons before being sent home after administrators found an online threat.
Adams County School District 50 spokesman Jason Kosena declined to release details of the threat Wednesday, including whether administrators found it on a social networking site or blog.
School officials locked down the school and called for extra law enforcement at around 7 a.m., about an hour after students arrived for first period.
Kosena says the school remains locked down as sheriff's deputies search the school.
The threat comes a day after the 11th anniversary of the shootings at Columbine High School, where two teenage gunmen killed 12 students and a teacher.
