Police said Dahiya was at a party with some of his friends serving in Indian Foreign Services and Indian Revenue Services at the Foreign Club Institute on Monday evening. Sources said that around midnight, about 10 people who were left at the party made a decision to enter the pool. "We suspect the facts stated by police and demand stringent probe".
When a woman officer slipped and fell into the pool, Dahiya and others jumped into the pool to save her. She was pulled out safely, but everyone soon realized that Mr Dahiya was still in the pool.
His body was found floating in the pool a few minutes past midnight.
A 2016 batch IAS officer, who came 53rd in UPSC's all-India ranking, drowned in a swimming pool late Monday night. They were in a shock and were left wondering as to how an ace swimmer like him-he had once swum across the reservoir of the Bhakra Nangal dam in Himachal Pradesh-could drown in a small pool.
Dahiya's family lives in Haryana's Sonepat.
Ishwar Singh, Deputy Commissioner of Police (South), said, "Prima facie, the team that carried out the post-mortem has said that the death was due to drowning and there were no injuries on the body".
Police officers had earlier mistakenly described the dead man as a trainee IAS officer. A family member said he was to join his service in Srinagar on Wednesday as an assistant collector.
He is survivied by a wife who is a doctor by profession.
Singh also told that Ashish had also won the director's gold medal a fortnight ago during his IAS training.
