The search was initiated in response to a threatening phone call made to the Philippine Airline cargo office at the airport at around 2:30 p.m. Tuesday, Sgt. Michael Rodriguez said.
Employees of the cargo office notified police, he said.
The threat was unsubstantiated and did not specify a particular flight or airport but police “wanted to err on the side of safety,” Rodriguez said.
Flight No. 104, which was traveling from Manila to San Francisco, landed at the airport at 7:20 p.m., Rodriguez said.
The aircraft was met by police, who escorted the plane to a remote section of the airport, he said.
Once there, the 337 passengers and 20 crew aboard were taken off the plane and bused over to the airport’s federal inspections area, he said.
The cargo was removed from the plane, Rodriguez said, and was investigated by a police explosives team, which included the trained canines.
The passengers were waiting for their luggage which was being transported from the remote site to the building as of 12:15 a.m.
