Death was a result of multiple organ failure due to anaemia, suggesting long-term neglect.
The 60-year-old mother of two siblings who allegedly abused their Indonesian maid to death has been remanded for seven days to facilitate investigations into the case.
The woman was arrested at Jalan Green Hall in George Town at about 2.30pm on Monday, two days after her 39-year-old son and 36-year-old daughter were detained.
The woman was nabbed in front of a lawyer’s firm.
She was believed to have gone there to seek legal assistance for her two children.
Looking frail and wearing a blue dress, the elderly woman arrived in a police truck at the courthouse at 9.35am.
She struggled to get down from the back of the truck and had to be assisted by officers on duty.
The case is being investigated under Section 302 of the Penal Code for murder.
On Saturday, the terrified victim Adelina Lisao, 26, was found sitting in the porch of a house in Taman Kota Permai with a swollen head and face, as well as injuries on her arms and feet.
Neighbours alleged she was forced to sleep with a Rottweiler outside the house for over a month.
She was admitted to the Seberang Jaya Hospital on Sunday but passed away shortly after.
Central Seberang Prai OCPD Asst Comm Nik Ros Azhan Nik Abdul Hamid said a post-mortem on Adelina found that her death was a result of multiple organ failure due to anaemia.
“The failure of the organs could be due to lack of blood as she was neglected,” he said.
Neighbours had also claimed that the maid was poorly fed.
The Indonesian Consulate-General’s Consular Affairs consul Neni Kurniati said they were trying to locate Adelina’s home in Indonesia as there were inconsistencies with the address in her passport.
“We are searching for the exact address in Nusa Tenggara Timur, and not in Medan as reported earlier.
“Based on the passport, she had been working with the present employer since December 2014,” Neni said.
She said the consulate was checking with the Immigration Department whether Adelina, who was hired through an agency, had a work permit.
“Her body will be taken back to Indonesia for a proper burial once investigations are completed,” she added.
