A maid faces three years in jail for adding urine and dirty wash water to her employer’s tea.

The 22-year-old who was working in Hong Kong, China, was arrested after her employer noticed the tea had strange odour.

She confronted the maid, who admitted to tampering with her drink, although the reasons are unclear.

The maid now faces a jail term for ‘administering noxious substances’ – urine and dirty laundry water are potentially hazardous to human health, reported Shanghaiist.

The identity of the maid and her employer are not known.

Last year a maid in the UAE who added urine to her employer’s tea was jailed for two months.

The 26-year-old Indonesian housemaid was found guilty of endangering the life of a family by the Dubai Court of Misdemeanours.

The maid carried out the crime in order to make the family like her, records say.
