SEATTLE, Wash. — Two F-15 jets from the Oregon Air National Guard have escorted an Alaska Airlines flight into Seattle, where the FBI was waiting Thursday night to interview a passenger who had been mentioned as a possible threat.

FBI spokesman Tom Simon in Honolulu says a caller told his office on Thursday afternoon that a man aboard Alaska Flight 819 from Kona to Seattle was a possible hijacker.

Alaska Airlines spokesman Paul McElroy says law enforcement boarded the jet through rear stairs when it landed about 7 p.m. in Seattle and took the unidentified man off the plane. McElroy says the flight was uneventful.

Seattle FBI spokeswoman Ayn Dietrich said the man was cooperative and was being interviewed. She said there doesn't appear to be any imminent public safety threat.

Simon declined to release any details about the caller who said the man was a threat.
