Pakistani authorities are set to hang a man who says he was 15 when he was arrested for a murder he claims he did not commit, lawyers said yesterday, in the latest case to shine a spotlight on Pakistan's crumbling criminal justice system. Ansar Iqbal says he was 15 when he and a friend were arrested 16 years ago for the murder of a neighbour, which the victim's family said was over an argument at a cricket match. Pakistani law forbids the execution of juveniles, but the country's courts have refused to examine Iqbal's school records and birth certificate because they say they were submitted too late.
