A Hong Kong woman was arrested on Monday on suspicion of abusing her Indonesian maids in a case that has sparked widespread outrage and drawn fresh attention to the risks faced by the migrant community. A housewife surnamed Law, 44, was arrested at the airport when she was trying to leave for Thailand, Hong Kong police said at a briefing. Erwiana Sulistyaningsih, a 23-year-old maid who said she had been badly beaten by her employer, is recovering at a hospital in Sragen, a city in central Java, after flying out from Hong Kong in early January.
