Missing Nida Ul-Naseer search widens in Newport
7 January 2014 Last updated at 20:04 GMT
Missing teenager Nida Ul-Naseer was upset before her disappearance because her family's asylum-seeker status barred her from attending university.
Her sister Shamyla made an emotional appeal at a press conference for the 18-year-old from Newport to return.
Sixth-form student Nida, from Pill, whose family is appealing a failed asylum bid, disappeared 11 days ago.
Police are checking her phone, computer and bank account records and have also begun searching three sites in the city- the Transporter Bridge, Lysaght Institute, and Pill Millennium centre.
