Classes at Sun Prairie High School are canceled Friday after the school received a bomb threat, officials with the Sun Prairie School District said Thursday.

School administrators and police made the decision to allow time for a "thorough investigation and comprehensive search of the facility," according to a brief statement on the district's Web site.

Anyone with information about the threat can call the high school principal at 608-834-6717 or Sun Prairie police at 608-837-7336.

All other district schools and the Alternative Learning Center will be open.
