An Indonesian maid faces up to one year's jail and a fine for adding menstrual blood to her employer's coffee.
Jumiah, 24, allegedly committed the act of mischief at a flat in Choa Chu Kang in August 2011.
She had been working for Mr Phang Nyit Sin, 38 for about a year.
She told the court she intends to plead guilty.
The case will be mentioned again in a week's time.
