Cleaners found a newborn baby boy in a toilet garbage bag being unloaded from a jetliner that had just arrived in Manila from the Middle East Sunday, reports said.
The infant is in good condition and a search has now begun for the mother, who investigators are convinced gave birth in the toilet as the Gulf Air jet flew to the Philippines from Bahrain, Britain's Daily Mail reported.
"She appears to have left the aircraft as soon as possible after the plane landed," the newspaper quoted a police officer saying.
Reports said the baby was found covered in blood and toilet paper when a security officer noticed something moving in a toilet garbage bag being unloaded from the plane.
The baby was rushed to a medical clinic in the airport where he was examined, cleaned up and given a bottle of milk.
Airport photographs show the baby wrapped in a towel while doctors and nurses warmed him up under a light bulb.
Officials at the airport said they had named the child George Francis - based on Gulf Air's airline code, GF - as efforts began to find the mother.
"We haven't been able to determine the nationality of the child at this stage — whether her mother or parents are from Saudi Arabia or the Philippines." according to one official quoted by the Daily Mail.
Many Filipinos work in Saudi Arabia and the Gulf states.
Authorities said they were baffled as to how the woman had managed to conceal the in-flight birth from other passengers and return to her seat without drawing attention to herself.
Officials said they were also surprised that no one else who had used the toilet noticed anything unusual.
