An Indonesian domestic worker has been remanded in custody pending a trial after she was accused of mixing urine in a bottle of water for her employers’ son in Hong Kong.

The defendant Komsatun, 40, was charged with one count of “administering poison with intent to injure” and appeared at the Kwun Tong Magistrates’ Court for first mention on Saturday, the Oriental Daily reported. No plea was taken.

The court heard that on April 11, the defendant gave a bottle of water which allegedly had urine in it to her employer’s 12-year-old son at the employer’s home in Ap Lei Chau on Hong Kong Island.

The boy drank the water but said the bottle had a strange odor. He complained to his mother.

The female employer questioned the worker and secretly taped their conservation as evidence. Then, the employer reported the case to police, who later arrested the Indonesian woman.

The court was told that Komsatun had been fired and that she now has no permanent place to live.

The magistrate rejected an application for bail by the defendant. She was remanded in custody till May 27, when the case will be transferred to the Eastern Magistrates’ Court.

Tests will be done of the bottle which allegedly had water mixed with urine – it will be sent to a laboratory for examination.
