An Indonesian maid has told a Hong Kong court that she was tortured for six months by her former employer , who shoved a vacuum cleaner tube into her mouth , tearing her mouth . In two days of disturbing testimony , Erwiana Sulistyaningsih , a 23-year-old domestic helper , said through an interpreter she endured all sorts of abuse , including being punched , slapped , kicked and beaten unconscious . The case sparked international outrage when gruesome images of her injuries surfaced earlier this year and she was admitted to a hospital in Indonesia in critical condition . Erwiana 's former employer Law Wan-tung , a 44-year-old housewife , faces 21 charges , including inflicting grievous bodily harm , assault and criminal intimidation . Law pleaded not guilty to all charges , except one , for failing to take out an insurance policy for an employee . Stripped naked . Speaking calmly , Erwiana described an incident when she said she was punished for dozing off during work . `` I was taken to the bathroom and she took off all my clothes and she sprayed cold water on me , '' she said . She said she was not allowed to put her clothes back on , and her employer switched on an electric fan and pointed it at her for hours before she was allowed to dress herself . Prosecutors accused Law , a mother of two , of using a mop , ruler , and coat hangers to beat Erwiana and also pulled her down from a ladder while she was cleaning . Erwiana said on one occasion she was beaten unconscious , and after she came to , her employer forced her back to work . `` She often punched my eyes and I was shocked . And she kept on punching and punching me , '' says Erwiana . Erwiana said she was forced to work for 20 hours a day , and was only allowed to sleep between 1 p.m to 5 p.m. `` I had to sleep on the floor , '' says Erwiana . All she was given to eat was three to six pieces of bread and a bowl of rice each day . Call for justice . Several migrant rights activist groups rallied outside the Wanchai District Court on Monday , calling for justice for Erwiana . The case also involves charges of assault on two other Indonesian domestic helpers , Tutik Lestari Ningsih and Nurhasanah , who were under Law 's previous employ . She could face up to seven years of imprisonment for the charges of causing grievous bodily harm , the maximum term the District Court can sentence . In January , thousands of people marched to the streets in support of the allegedly abused young Indonesian worker.Amnesty International issued a public statement in June urging the Hong Kong government to take immediate action to `` end the widespread abuse and exploitation of migrant domestic workers . '' According to a report released last year , Indonesian migrant workers are at risk of serious human rights violations in Hong Kong.Hong Kong employs some 320,000 foreign domestic workers mainly from Indonesia , Philippines and from other parts of Asia.READ MORE : Indonesian migrant worker tells of abuse as thousands protest in Hong Kong .
