DENVER (Reuters) - School officials on Thursday called off classes at Columbine High School, the scene of
a student massacre in April, after a student received a ``credible threat'' over the Internet.
Jefferson County Schools district spokeswoman Marilyn Saltzman said a student called the school and
reported receiving a threat over the Internet. She said she had no details, but that it was considered a
``credible threat'' and officials decided to close the school.
