The husband and friends of Ms Rachelle Lieng Siong Chung For Yuen, 27, form Mill Hill, London, handed out leaflets across the West End and at stations and hospitals in London in a desperate attempt to find her. "She was travelling from Mill Hill and would have gone through King's Cross," one friend told BBC News. It appears that Ms Chung For Yuen, an accountant who was originally from Mauritius, was killed in the explosion between King's Cross and Russell Square stations. Courtesy BBC News
