A spokeswoman for Philippine Airlines says a telephoned bomb threat that prompted authorities in San Francisco to search a plane from Manila was a hoax.
Cielo Villaluna says all 337 passengers and 20 crewmembers were taken off the plane and searched after it landed Tuesday night and was moved to a remote part of San Francisco International Airport. No injuries were reported among passengers or the crew.
She says authorities ended the search after not finding any threats.
Police Sgt. Michael Rodriguez has called the threat "unsubstantiated."
Villaluna says the anonymous call was made to the airline's cargo warehouse in the San Francisco Bay area.
