Guard claims rapes, attacks on detainees unpunished Explosive claims of rapes among detainees and disturbing violent incidents including two escapes, a violent protest against the centre doctors and a slashing attack, have been revealed by a detention centre guard. The Papua New Guinea national who asked not to be identified for fear of losing his job also alleged that G4S - the security company running the centre - was making huge profits by exploiting local labour and paying meagre salaries of about $40 a day. Exposed: A Manus Island security guard has revealed rapes and disturbing violence. The revelations of violence back up claims made by the centre's former occupational health and safety head Rod St George and come as Immigration Minister Tony Burke flew in to Manus to inspect the controversial centre. The guard says reports had been made about the incidents but he did not see any investigations and PNG police were not informed. He said in the worst incident in May the PNG nationals working for G4S were asked to go to the single men's quarters and help remove a badly injured man who had been raped. The victim, he says, was a Pakistani national who had been raped by six Middle Eastern men. "We had to go into the tent and he was there and it was very bad," said the guard. There was excrement all over the tent. He said the man spent about two weeks in the camp clinic before being sent back into the single men's compound where his attackers could roam freely. The guard said he did not understand why the man was put back into the same compound, in his own tent. "Nothing happened to them [the suspected rapists]," he said. It's not a good thing. Mr Burke said it was difficult to investigate claims of abuse unless people came forward with the names of alleged victims and perpetrators. "There are challenges for the police in dealing with an allegation where no complainant has come forward and the only person who it is thought might have been a complainant has left the country voluntarily some time ago," Mr Burke said, after visiting the centre and talking with some detainees. He vowed that operational changes would be made to minimise the likelihood of assaults or abuse, including segregating aggressive detainees or those who were particularly vulnerable. The guard said another incident involved an attack by a detainee on another in a bathroom area. He said one detainee had walked up to another and slashed his shoulder with a sharp object like a knife. He had to go to the clinic. The cut went from his shoulder down to his buttocks," he said. The guard said reports were filed but he did not think any significant investigation had occurred. He also detailed three different incidents where detainees had escaped the centre including one extreme case when about 20 men had launched a major protest. "They were pushing and they got the gate into the men's compound off its hinges and they marched down the road to the clinic," he said. They were chanting, 'Panadol, Panadol,' because they were angry that that was all the doctors would give them for all their medical conditions - even if they had heart pain. The doctors were scared. They locked themselves in the clinic. In another incident, detainees scaled the fence and swam away - only to return after swimming barely 20 metres. With Michael Gordon
