South Korean police investigating the case of a three-year-old girl who was left to starve to death at her home have arrested the child's biological mother and sister.
The little girl's remains were found at an apartment in the city of Gumi on February 10 and investigators believe she died from starvation some six months earlier.
But the story took a bizarre turn when DNA tests revealed in March the girl's apparent mother who was arrested, identified only by the name Kim, turned out to actually be the victim's biological sister.
Investigators found the victim's apparent grandmother, 49-year-old Seok, was actually her biological mother and had unloaded her newborn onto her eldest daughter for her to raise with her then-husband.
DNA testing also revealed Seok's husband was not the child's biological father.
Police are currently trying to work out the father's identity.
Investigators believe after Kim divorced her then-husband, Hong, in April last year, she allegedly abandoned her younger sister to her fate in her apartment and went off to live with a new man.
To confuse matters further, local media also report Kim had given birth to a child of her own about the same time as her mother.
The alleged child's whereabouts is unknown and police are currently searching for them.
As the effective guardian of the toddler who died of starvation, Kim faces charges of child neglect.
Seok was arrested on March 10 and both suspects remain in preventive detention as the investigation continues.
