A dead body was discovered at Kennedy Airport Sunday morning, officials said.

The body of a 51-year-old man was found in a restroom inside Terminal 8 around 11 a.m., the Port Authority said.

The man’s body was removed from the building and turned over to the Medical Examiner’s office for an autopsy.

The man worked for a private company that operates a kiosk inside the airport, officials said.

It’s not immediately clear how the man died, but a PAPD source said it appeared to be related to natural causes. No criminality is suspected.

Terminal 8 is the largest passenger terminal in the JFK airport and includes dozens of food and shopping outlets.
