Mauritius airport staff found an abandoned newborn boy in the trash can toilet of the aircraft toilet.
A 20-year-old woman from Madagascar was arrested on suspicion of giving birth on a plane.
The Air Mauritius plane that arrived from Madagascar landed at Sir Sivosagur Ramgoolam International Airport on January 1.
Airport officials discovered this during routine customs inspections of the aircraft.
They sent the baby to a public hospital for treatment.
The woman suspected of being the mother of the child initially denied that the boy was hers, and she was required to undergo a medical examination, which confirmed that she had just given birth.
She was monitored by the police in the hospital.
It is said that she and the baby are doing well.
The Malagasy woman arrived in Mauritius with a two-year work permit. After she was discharged from the hospital, she will be questioned and charged with abandoning her newborn baby.
