Riju Ghosh (18) who joined the institute on August 9, is under treatment at Nutangunge home in Bankura. According to his family, he is heavily sedated and not in a condition to give a statement. A student of Computer Science, Riju was taken home by his family on Monday morning. An FIR has been filed on basis of a complaint by his father Subir Ghosh, which names two students — Kaushik Chakraborty, a second year student of BCA and Aritra Bhattacharya of Electronics and Communication Engineering department.

According to the complaint, Riju had been subjected to physical and mental harassment for days.

“After a few days of ragging, Riju was running a high temperature,” said Ghosh. “After thrashing him, his seniors would thrust his face into a toilet pot and repeatedly pull the flush. Such torture is so inhuman.”

According to Ghosh, when he telephoned his son, he would admit to being subjected to ragging. “But his seniors apparently told him that to study engineering he had to tolerate it.”

Ghosh said he had sent his only son all the way to Siliguri for higher education and has spent about Rs 90,000, but now he is not sure whether he can send him back to the college.

“We have information that the students against whom the complaints have been filed, are not in the college,” said D P Singh, SP Darjeeling. “We will have to verify the complaint and based on legal provisions related to ragging, we will proceed in this case.”

Efforts to contact the college authorities were in vain.
