'Justine had conveyed to his hostel mates 2-3 days back that he was suffering from some chest pain. He could have died perhaps due to a cardiac arrest inside the pool. But the exact picture would be clear only after the post mortem report is received,' Amity University Vice President (Corporate Communications) Savita Mehta told IANS.

Justine was good at sports and jogged daily, his classmates said.

He was admitted to the college in the last week of July and was staying in the college hostel since early August.

Justine was pursuing a dual degree (B. Tech and M. Tech combined) in space and avionics engineering programme. His father works with a private firm in Saudi Arabia and mother lives in Mumbai.

'A post mortem is yet to be conducted on Justine's body as his parents are yet to arrive. His father has been informed. One of his uncles staying in Maharashtra is expected to arrive. His mother is also expected to reach,' said Superintendent of Police city A.K. Tripathi.
