A 38-year-old man meted out retribution in the most macabre form to his friend on Tuesday night. He killed his friend by chopping off his private parts after his sister alleged that she had been raped by him. He then surrendered before the Pant Nagar police in Ghatkopar (East).

The Pant Nagar police were shocked when a man came to the Kamraj Nagar police chowky, chopper in hand. Identifying himself as Kannan Muttu Kumar Swami Pillai, he proceeded to admit that he had killed his friend Govindan (35).
