Judges in Pakistan have ruled that a top scientist arrested last year for allegedly being involved in leaking nuclear technology should have his detention extended for a further three months.
The scientist, Mohammad Farooq, worked at the research laboratory headed by Abdul Qadeer Khan.
Mr Khan is seen as the father of Pakistan's nuclear bomb and has admitted selling the nation's nuclear secrets to other countries.
Mr Farooq is the only employee from the laboratory who remains in custody - more than 10 other scientists and officials originally held as part of the investigation have been released.
AQ Khan himself was pardoned earlier this year by the Pakistani President, Pervez Musharraf.
