A TRAINEE diver whose decomposed body was recovered three days after he went missing at Pulau Hantu had a scuba tank that was filled with toxic gases.

Mr Sue Qing Wen's body was found floating in the sea off the island on Feb 20 last year with the compressed air tank still strapped onto his body.

The tank, which should have contained 80 per cent oxygen and 90 per cent nitrogen, was found instead to have 785 parts per million (ppm) of carbon monoxide and 12.3 ppr of hydrogen sulphide.
