SANDAWALA (AFP) - Police said on Sunday they were seeking extradition of an American man suspected of murdering his daughter and her British-based husband during a family holiday this month. Uzma Naurin, 30, a US national, and her Pakistani husband Saif Rehman, 31, were killed on November 1 in Lala Musa, on their way back from a shopping trip. Naurins father, 58-year-old Muzaffar Hussain, who was in hospital on the day of the killings, has since fled to the United States but is now the chief suspect in the murder case, police told AFP on Saturday. We have gathered evidence against him. We will present a detailed report in court and try to get red warrants (extradition) against him, said Nasir Mehmood Butt, head of the investigating police station in Gujrat. Once we get him into custody, we will be able to obtain all the information and this case will be solved, he said. Naurin married Saif without her familys permission in the British city of Manchester but relatives later attended a full wedding ceremony in the Scottish city of Glasgow, where Saif was based, earlier this year.
