Four to Appeal in Gang Rape Case

After being convicted for Delhi bus attack.

The four men convicted in the Delhi gang-rape case that ignited protests across India are appealing their sentences. Mukesh Singh, Vinay Sharma, Akshay Thakur, and Pawan Gupta were sentenced to death last month. The men and lawyer AP Singh have maintained their innocence in the December attack of a woman, 23, who died two weeks later. “They could take their appeal all the way to the Supreme Court and also ask the president for clemency–a process that could take years,” according to the BBC.
