Rocky Yadav, the son of a Bihar politician, has been given the life sentence for shooting a high school student in a case of road rage last year. Mr Yadav, 26, was convicted last week by a court in Gaya, where he lived and opened fire last May on Aditya Sachdeva, a 19-year-old who was driving a Maruti Swift borrowed from his father to celebrate the end of his exams.
