The Northern Territory Police Force is continuing to investigate the death of a 27-year-old man on Galiwinku over the weekend.
Police can confirm that the 19-year-old male who was arrested on Saturday, has been treated at Royal Darwin Hospital and has since been released from custody pending further investigations.

During that altercation, the 27-year-old is believed to have suffered a critical injury.
The 19-year-old suffered a laceration to his wrist.
A number of disturbances were reported after the death. Around 5:45pm on Saturday police received reports of a fire at a residence within the community with no injuries reported. A short time later a disturbance was reported within the community. An ambulance, driven by police, was allegedly damaged with rocks and other objects.
