A Manus Island asylum seeker who set himself on fire will be charged with attempted suicide and arson by Papua New Guinea police.

Under the PNG criminal code, attempting suicide is considered a misdemeanour which carries a penalty of up to one year in prison, whilst arson can result in a sentence of up to life in prison.

The chief of Manus police, Inspector David Yapu, says the incident was the fourth deliberately lit fire at the refugee centre and says incidents of suicide and self-harm were beyond the control of police.
