A Saudi couple tortured their Sri Lankan maid by hammering 24 nails into her hands, legs and forehead, after she complained of a too heavy workload, officials said today. Nearly 2 million Sri Lankans sought employment overseas last year and around 1.4 million, mostly maids, were employed in the Middle East. Many have complained of physical abuse or harassment. LT Ariyawathi, a 49-year old mother of three, returned home on Friday after five months in Saudi Arabia.
