"There are about 6,300 students at IIT-Kanpur. We can't keep an eye on all of them whether they are in their rooms or moving around on rail tracks," Students Welfare Dean Prof A K Ghosh said.
He said the student's body has been handed over to his parents, after a post-mortem.
The body of G Sai Kumar Reddy (20), a resident of Prakasham district in Andhra Pradesh, was found along the Kanpur-Farrukhabad railway line on January 1.
Reddy's family believes the student was not under any mental agony or pressure and he has not left any suicide note either, he said.
The police report also says it could be an accidental death, he added.
Asked if it was, indeed, an accident, then why a four-member probe panel has been formed, Ghosh said the committee will find out the truth about the incident.
According to an RTI reply, eight students have committed suicide at IIT-Kanpur between 2005 and 2010, but the institute never formed a committee to probe the incidents but only constituted fact-finding committees.
The institute said, in its reply to the RTI query, that they can't reveal the findings of the committee to media or public as it was its internal matter.
