The deceased, from Simbu province, was found hanging at one of the houses at Lawes Road, Port Moresby. She was discovered in the earlier hours of October 21.
Upon arriving at the crime scene, homicide detectives suspected that foul play was involved. This was due to bruises being evident hours after her death, including strangulation marks on her throat.
Officer-in-charge of the National Capital District police homicide unit, Ulagis Mantu, told this newsroom that the arrests were made according to investigations.
