A sessions court in Himachal Pradesh today convicted all four medical college students accused of ragging their junior Aman Kachroo. All accused were charged with culpable homicide not amounting to murder.A fast track court in Dharamsala held that 19-year-old Aman Kachroo was ragged to death by the four at the Rajendra Prasad Medical College and Hospital in Tanda. After hearing the case for more than 20 months the court has decided to convict the accused under section 304. Aman, a student of Rajendra Prasad Medical College and Hospital in Tanda, about 15km from Dharamshala died on March 8, 2009, after being allegedly ragged by final-year students. Prosecution led by senior public prosecutor Jiwan Lal Sharma pleaded that Aman was brutally beaten up under the garb of ragging by his four seniors and later he succumbed to his injuries. While, the defence counsel Abhimanyu Chopra, who concluded his arguments yesterday, contended that the deceased was a heart patient and a sudden cardiac arrest could have caused his death. Sharma said the court has recorded the statement of 38 witnesses, comprising doctors, police personnel and Aman's father Rajendra Kachru during the trial. The father of Aman Kachroo Mr. Rajender Kachru has expressed his satisfaction over the verdict but he also said that his mission will only be completed if the ragging is eradicated fully in the country.
