SEATTLE - King County has asked an alternative high school to move out of an old hangar at Boeing Field where it has operated the past nine years.

The Seattle Post-Intelligencer reports the principal of Opportunity Skyway, Cindy Ortega, says the 170 students are no longer welcome because of gang violence. One student was killed and three others wounded in the past month.

The county official who oversees the airport, Harold Taniguchi, says employees are concerned about their security.

The alternative school handles students who have been kicked out of other schools or have juvenile records. Last year 96 students graduated from the program, and all passed the reading and writing portions of the Washington Assessment of Student Learning.
