A dead man was found inside the toilet of a Gulf Air plane on Wednesday morning shortly after the aircraft landed at Manila's Ninoy Aquino International Airport (NAIA) Terminal 1.

The body has been identified as that of Marlon Cueva, an overseas Filipino worker (OFW) who hails from Lubang Island, Mindoro Occidental, according to a report in the Manila Bulletin.

Investigators said Cueva is believed to have committed suicide onboard the plane with flight number GF 154.

The victim was identified by Gulf Air local station manager Khaled Ahmed Abdulrahman based on the flight manifest. He was 36 and an electrician from Abu Dhabi.

NAIA 1 general manager Octavio Lina said initial reports show that the victim hanged himself.

“The injuries seem self-inflicted. He probably used a clothing article to hang himself. There were no ropes or wires. We will leave it to our forensics experts to establish the suicide. The lavatory was intact,” said Pasay City police chief Senior Supt. Napoleon Cuaton.

Witnesses account show the victim was restless and uneasy during the flight back home.

The body was discovered at around 11:20 am, shortly after the plane landed. A flight steward, conducting a routine check, found Cueva’s body inside the lavatory located at the tail-end of the plane.

A Filipino nurse sought to revive Cueva but failed to resuscitate him. Photos from the crime scene showed the body slumped along the aisle leading to the comfort room.

The victim, wearing a black jacket and a blue polo shirt, apparently died of asphyxiation or lack of oxygen.

The plane’s flight for the afternoon has been delayed pending investigation.
