A 23-year-old student from Mumbai died after falling off a building terrace on the IIT Kharagpur campus on Saturday.Police sources said Nikhil Bhatia, a final-year mining engineering student and resident of Vidyasagar Hall (hostel), was last seen by his friends on Saturday morning while brushing teeth and having breakfast. He later went to Lal Bahadur Shastri (LBS) Hall to meet a friend.“Around 11.15 am, I was informed that a student had fallen off LBS building,” said Debashis Chakraborty, associate professor (mining engineering) and faculty adviser. Staff and students of LBS Hall rushed out on hearing a loud thud and found Nikhil sprawled on the ground. They rushed him to the hospital on campus, where he was detected with serious fractures on both legs and other injuries and referred to West Bank Hospital in Howrah , 125km away.A West Bank spokesperson said, “Nikhil was brought in the afternoon with injuries. Doctors found him dead on arrival. It is suspected that he suffered internal haemorrhage.” Initially, police said they were probing if he fell off accidentally, jumped off or was pushed by someone and wait till they could speak to him. Later, they lodged a case of “unnatural death”.Chakraborty said Nikhil was suffering from depression and was taken for counselling around six weeks ago. “We informed his father, a senior officer at a nationalised bank, who came down from Mumbai and took him back home,” Chakraborty said, adding that he returned a few days ago and sat for an exam.
