The incident took place on June 21 when unidentified assailants who were in a car allegedly opened fire on a motorbike in which Rajan and his father Kailash were travelling. While Kailash died on the spot, Rajan sustained three bullet injuries, a police official said.
Rajan is a black belt in taekwondo and has participated in national-level competitions. The bullet injuries caused severe nerve damage, for which his one leg was amputated on Wednesday and the other two days later, said the official.
