A 24-year-old Myanmar woman was arrested by police for murder three hours after a 70-year-old woman was found lying unconscious in a pool of blood. The victim, who was discovered at her home at Choa Chu Kang, Singapore, was pronounced dead on Monday.

The deceased, named as Mehrotra Shashi, had lived with her daughter, son-in-law and two young granddaughters at a flat on Choa Chu Kang North 6 for the past 17 years, Shin Min Daily News reported.

The accused Zin Mar Nwe is a domestic worker from Myanmar who two months ago was hired to look after the elderly victim and the young girls.

At 3:09pm on June 25, the family called for police assistance after finding Ms Shashi lying unconscious in a pool of blood. She appeared to have multiple wounds, and their domestic worker was not home.

Paramedics arrived at the scene and shortly after pronounced her dead at 3:29pm. The victim was reportedly stabbed many times mainly in the neck and chest.

Around three hours after the alleged murder, officers arrested the accused at an undisclosed location.

The crime scene was sealed for 12 hours during the collection of over 30 bags of evidence. However, it is understood that the alleged murder weapon has not been recovered.

The maid was remanded for a week for psychiatric evaluation. No bail will be offered as it is a capital case. If found guilty of murder, the accused could face the death penalty.
