Saudis traveling to Pakistan for kidney transplant surgeries have been warned against paying money to middle men who con people by promising to arrange for kidney transplants, the Ministry of Interior said Monday quoting the Saudi Embassy in Pakistan. A citizen paid $45,000 for his father's transplant to a con man who simply disappeared after receiving the money, the statement said. The Ministry urged all citizens not to pay any amount to middle men for the sake of their own safety.
