NEW DELHI: An Indian court Tuesday ordered the execution on January 22 of four men convicted of the infamous 2012 gang rape and murder of a Delhi university student. Six people were originally charged with taking part in the brutal attack aboard a city bus, but one was released after a brief detention as a juvenile, while another committed suicide while awaiting trial. On Tuesday Delhi court judge Satish Kumar issued a warrant ordering the four on death row to be executed on January 22 at 7am. The condemned men still have one avenue of appeal remaining, and they can also petition the Indian president for mercy. Jyoti Singh, 23, was attacked in December 2012 while returning home after visiting the cinema with a male friend.–Agencies
