Violence in Australian town after arrest of man over girl's murder

Warning for Aboriginal and Torres Strait Islander readers: this article contains references to someone who has died.

There has been violence outside an Australian hospital where a man suspected of murdering a five-year-old girl was being treated.

Jefferson Lewis was arrested late on Thursday night local time in Alice Springs, after being seen by members of the local community and reportedly attacked.

Video shows dozens of people gathering outside the town's hospital, some throwing projectiles, with police using tear gas.

The body of the girl, who is identified only as Kumanjayi Little Baby for cultural reasons, was discovered earlier on Thursday.

She had last been seen on Saturday, when she was put to bed at an Aboriginal town camp near Alice Springs just before midnight.

Australia's national broadcaster, the ABC, reports the crowd of about 400 Aboriginal people outside the hospital yelled that Lewis needed to face "payback" and accused the police of protecting him.

"Payback" is term for traditional punishment under Aboriginal law in Central Australia.

Many were chanting that he should be killed for his alleged attack on Kumanjayi Little Baby, the ABC added.

Video from the scene shows crowds throwing items towards police and items being thrown. Several police vehicles appear to have been damaged.

Northern Territory Police Commissioner Martin Dole told the ABC Lewis was unconscious when officers found him.

Dole said about 200 people turned on police and paramedics as they responded to reports Lewis was being assaulted.

Several people including members of the emergency services were injured, but no arrests have been made over the violent disorder.

Dole said the scenes outside the hospital were "not acceptable" and were not "reflective of what we've seen from the community of Alice Springs in the last five days".

Lewis has been flown from Alice Springs to Darwin and has been taken into police custody, Dole said.

Charges are expected to be laid against Lewis in the coming days, Dole said.

Forensic test to confirm the young girl's identity and cause of death will continue on Friday.

Police had been combing nearby bush and desert for Lewis, who was released from prison six days before Kumanjayi Little Baby disappeared and vanished around the same time.

Dole said everyone involved in the search for her had been holding out hope of finding her alive.

"When we made that discover yesterday [it was] absolutely devastating for everybody involved," he said.

In a statement, Kumanjayi Little Baby's mother - who was not named - said her daughter was loved and missed.
