Representatives of the boat operators, Dive Pro Liveaboard, also repeatedly tried to push people into signing waivers – say survivors – which would have seen them agreeing to the statement: “I do not accuse anyone of any criminal wrongdoing.”

Justin Hodges, an American diver who was also rescued, told us the “release of liability document”, written in English, was handed to him as he was giving his witness statement.

He said he had thought the person he was talking to was “an official”, but at this point learned that he worked for the company.

“He slid in with the authorities,” says Justin. “The fact he tried to get us to release liability at that moment was insane to me.”

At least some of the people we spoke to didn’t sign the document.
