Indonesia's President Susilo Bambang Yudhoyono has expressed his concern and anger over the alleged torture of an Indonesian maid by her Hong Kong employer.

In a telephone call Tuesday with Erwiana Sulistyaningsih and her father, Rohmad Saputra, the Indonesian leader also promised to help both overcome the ordeal.

On Monday, Hong Kong police arrested a 44-year-old woman, surnamed Law, in connection with the alleged brutality. A day earlier, thousands of maids and their supporters protested in Hong Kong over the case.

Sulistyaningsih, 23, returned to Indonesia early this month and is being treated at a hospital in Central Java town of Sragen.

Yudhoyono says he has communicated several times with Hong Kong leaders to ensure a good working environment for Indonesian workers there.
