Police in Dubai said Saturday the recently hired maid and two men were arrested last week on suspicion of stealing from the Asian family's villa in Bur Dubai, Gulf News reported.
Police became involved Aug. 17 when they received a report that the 50-year-old man, his wife and 14-year-old daughter were suffering from what appeared to be food poisoning after dining out. Medical tests showed, however, the symptoms were caused not by tainted food but by strong narcotic pills the maid allegedly placed in the family's tea.
The mother and daughter were hospitalized, the Dubai newspaper said.
"According to the medical report, the pills could have caused the death of the family," Lt. Col. Turki bin Faris said.
After recovering from his symptoms, the father discovered gold jewelry and other valuables were missing from the home, Gulf News said.
The officer also said the maid had been hired without proper sponsorship and the family had failed to obtain valid proof of the woman's identity.
"The crime began when the victims hired an absconding domestic helper who is not on their sponsorship," bin Faris said.
"The father acknowledged that he had hired a housemaid who is not on his sponsorship but she used to come to his house on a daily basis to work and left at night. The housemaid started working with the family only six days before the crime.
"Despite the scarcity of information provided, police were able to reach her residence and arrested her with her partners."
The maid allegedly confessed to taking part in the robbery scheme.
