Farouk Abdulhak, 35, remains holed up in Yemen and has refused to come back to the UK where he is accused of the rape and murder of 23-year-old Martine Vik Magnussen.
Martine Vik Magnussen was found dead in a basement in Westminster, central London, after a night out with friends to celebrate coming top of the class in her exams in 2008.
The suspect, aged in her 60s, was held by Metropolitan Police officers yesterday in Westminster in an apparent breakthrough in the investigation into the death of Martine Vik Magnussen.
