Classes at a Colorado high school are canceled and students have been searched for weapons and sent home after administrators found an online threat.
A spokesman for the Adams County School District would not release details of the threat at Westminster High School, including whether administrators found it on a social networking site or blog.
Officials locked down the school and called for extra law enforcement at around 7 a.m. Spokesman Jason Kosena says the campus remains locked down as sheriff's deputies search the school.
The threat comes a day after the 11th anniversary of the deadly shootings at Columbine High School.
Westminster is about 12 miles north of Denver.
