Supri, who like many Indonesians has only one name, says in a phone interview with National Geographic that the captain attacked him five times. The assaults, Supri says, included his being locked in a freezer when he was still wet from having taken a shower, and being beaten, sprayed in the face with a hose, and shocked with an electric stun gun.

He recalls that after about 15 minutes of begging to be let out of the freezer, he heard another crew member tell the captain that Surpri could die. Supri says the captain’s response was: “Let him die.”
