IITK PHD Student Commits Suicide

Update: According to the newspapers, this one does not seem to be due to the academic stress.

Another suicide at IITK, this time by a Ph.D. student and the vews reports are very cryptic at the moment. This one is from DNA through PTI:

KANPUR: A PhD scholar from Kerala, pursuing doctoral studies at the Indian Institute of Technology (IIT) here, allegedly committed suicide by consuming cyanide.

The body of Abhilash J J was found at the terace of a hostel in the IIT campus on Monday morning, police said.

Some cyanide and a suicide note, which said he was under depression, were recovered.

Abhilash had recently visited Germany as part of his PhD programme and his viva voce was scheduled for November 9.

I wonder what the people at IITK are saying? What could have been the possible reason?
