Calcutta, March 27 :    Calcutta, March 27:  Worried over the rising incidence of violence, drug abuse and sex rackets in hostels, students of medical and engineering institutions in the city joined hands with veteran teachers and academicians on Wednesday and threatened to launch a united movement, demanding government measures to stop such malpractices. They urged the government to set up an inquiry commission to investigate malpractice in government-controlled hostels, such as drug abuse, sex rackets and screening of blue films. After discussing the problems with students, well-known retired teachers like Sunanda Sanyal, Amlan Dutta, Sibnarayan Ray and Swaraj Sengupta demanded that the government order a judicial inquiry into the death of Saumitra Biswas, fourth-year student of R.G. Kar Medical College and a boarder of Lalit Memorial Hostel, who was found hanging from the ceiling of his hostel room in August last year. Students of R.G. Kar Medical College, National Medical College, Jadavpur University and Shibpur Bengal Engineering College were present at Wednesday's discussion. Sanyal, Dutta and others present said they conducted investigations in a number of hostels and found that leaders of various political parties encouraged such illegal activities to wrest control over the students' unions. They demanded that the government stop political interference in educational institutions. 'Those who get admission in medical and engineering colleges do so by appearing in tough competitive examinations. Since we have spent several decades in the teaching profession, it is our responsibility not to allow the cream of our youth to be wasted in this way,' said the teachers. They attributed the deteriorating conditions of hostels to the lack of proper governmental care. Along with government hostels, they had conducted investigations in some private hostels too, and 'were happy to find that the standard of discipline in private hostels is far superior to that in the government-run ones.' Describing the R.G. Kar student's death as a glaring example of the grim situation prevailing in hostels, Sanyal and others present said they had reason to believe that Saumitra, an SFI activist, had to lose his life as he had identified one of his classmates who had allegedly superimposed a photograph of the face of a female classmate on a nude torso and displayed it on the Net. Supporting the teachers, the students said they would soon submit a joint memorandum to chief minister Buddhadeb Bhattacharjee, seeking his intervention.
