Asylum seeker Hamid Kehazaei was kept on Manus Island for a week waiting for approval to be medically transferred to Port Moresby despite showing signs of septicaemia that killed him, it has been alleged, as leaked documents reveal a pattern of medical negligence on the island including untreated skin infections, tooth decay and tropical diseases.

A worker on the island, who has asked not to be named, said Mr Kehazaei, who died from severe septicemia, had been kept for a week on the island by the International Health and Medical Service (IHMS) after cutting his foot.

Leaked documents reveal a pattern of medical negligence on Manus Island: Hamid Kehazaei died from septicemia.

This coincides with witness statements from asylum seekers who have written to IHMS complaining of Mr Kehazaei's treatment, as anxiety grips the centre following the 24-year-old's death.

One asylum seeker claims an IHMS staff member said there was nothing more they could do for Mr Kehazaei, once he was brought to IHMS. In a letter to IHMS, the asylum seeker said Mr Kehazaei's leg was swollen with pus and he couldn't walk. He also appeared "yellow" and was lying on the ground in the compound before being taken to the IHMS clinic. Mr Kehazaei, then in a wheelchair, told his friend he was concerned his leg would have to be amputated.
