Li Ye, a Chinese national, was handed one charge of murder in the state courts for allegedly causing the death of Lim Lai Guan, 56.
Charge sheets state that the incident occurred at about 1.38am (local time) on Wednesday morning at City Gate Residences along Beach Road.
Li, who is in remand, appeared in court via video link on Thursday. She was not represented by a lawyer.
While no indication of plea was taken, Li told the court: “It’s manslaughter. I did not intend to murder this person.”
No bail is offered, and the prosecution requested that Li be kept in remand for a week, to revisit the incident scene.
Li will return to court on May 16.
The police said in a media release on Wednesday that they were alerted to a call for assistance at a residential unit along Beach Road at about 2am that morning.
“Preliminary investigations revealed that a 56-year-old man was lying unconscious inside the unit,” said the police, adding that they arrested a 37-year-old woman at the scene.
A knife, believe to have been used in the incident, was also seized.
The man was taken to the hospital, where he subsequently died.
The police said that both parties were known to each other but further details of their relationship have not been revealed.
Police investigations are ongoing.
If found guilty of murder, Li faces the death penalty.
