The MP for Papua New Guinea's Manus Island says one of the men charged with the murder of asylum seeker Reza Barati has been granted bail.
23-year-old Mr Barati was killed during clashes at Australia's asylum seeker detention centre in February last year.
Two people have been charged over his death, while police are still looking for three more suspects.
MP Ronnie Knight says a local court has released Joshua Kavulia on bail with strict conditions that he not go near the detention centre or refugee transit facility.
But the Australian Associated Press has reported some refugees on Manus claiming that Mr Kaluvia has threatened to go after witnesses to Mr Barati's death.
But Mr Knight says he hasn't heard of this, and if anyone has any complaints they should go to the police.
"If he has threatened somebody, or he has approached somebody and made some sort of utterance that he is going to be a problem, that person has all the right to go to report into the nearest police station and he will be arrested as he has obviously breached the conditions of his bail and he will go back to the prison."
