19-year-old Aman Kachroo was ragged to death by four seniors

Four medical students, who were convicted of ragging their junior Aman Kachroo to death in a Himachal Pradesh college four years ago, have been freed before completing their four-year rigorous jail term.The students were freed after the Himachal Pradesh government decided to write off their remaining sentence on account of their 'good conduct' and allow them to complete their medical course at a medical college in Kangra. But they will be barred from government jobs.In 2009, Aman Kachroo, a first-year student at a medical college in Himachal Pradesh was severely and persistently ragged by seniors who were allegedly drunk. On March 7, 2009, his four seniors attacked him so brutally in the boys' hostel that he was rushed to hospital the next day.The post-mortem showed that the 19-year-old had died of a brain hemorrhage.A probe panel appointed by the Supreme Court after national outrage found that the teenager had repeatedly complained to the college and asked for help, but was ignored.

Ajay Verma, Naveen Verma, Abhinav Verma and Mukul Sharma were convicted and sentenced in 2010.Kachroo's death led to the introduction of new guidelines at colleges across the country to protect students from ragging.
