Sri Lanka is probing allegations that one of its nationals employed in Jordan was forced to swallow nails, in the third case involving alleged torture in three months, an official said.

A housemaid identified as D. M. Chandima has told the Sri Lankan diplomatic mission in Amman that her employer forced her to swallow six nails, an official at the Foreign Employment Bureau of Sri Lanka said.

“We are awaiting a full report from doctors,” the head of the bureau, Kingsley Ranawaka, said adding that the authorities would decide on the next steps after looking at the medical evidence.

The report came as another Sri Lankan housemaid who had been working in Kuwait accused her employer of driving 14 wire nails into her body as punishment for failing in her work.

The woman, identified only as Lechchami, 38, underwent surgery to have the nails removed after returning home to Sri Lanka, the director of the hospital in the northwestern town of Kurunegala said on Saturday.

The doctor said the woman had told surgeons that her Kuwaiti employers drove the nails into her hands and left leg -- some as long as 3.5 centimetres (1.5 inches) -- when she asked for her salary after working for six months.

Police said the case was under investigation.

In August, another housemaid complained her Saudi employer drove 24 nails into her arms, legs and forehead as punishment. Most of them were removed by surgeons in Sri Lanka.

The Saudi government and private sector officials in Riyadh have questioned the credibility of the woman’s allegations.

Some 1.8 million Sri Lankans are employed abroad, of whom 70 percent are women. Most work as housemaids in the Middle East while smaller numbers work in Singapore and Hong Kong, seeking higher salaries than they would get at home.
