Arun Krishna was pursuing MTech in Nano Technology at National Institute of Technology (NIT) in Kozhikode. He had been staying alone in his room for the last few days as his roommate had gone home for holidays.
His classmates told the police that there was nothing unusual about his behaviour. Arun, who was from Thiruvanathapuram, had joined the NIT in June.
The police are looking for possible reasons for his death. No suicide note was found, they said. Investigations are underway.
