The three children were later identified as siblings Rumana (7), Raja (5) and Sanya (4). They live with their parents in central Delhi’s Nabi Karim area, not very far away from the railway station, and were somehow stranded on Tuesday evening. It was the eldest sister, Rumana, who could recall the identity of a building (milestone) near her residence and they were finally handed over to their mother around 2.30 am, said Sanjay Bhatia, Deputy Commissioner of Police (Railways). He further said the children were located after 12 am, after which it took the police more than two hours to locate their residence.

He also rushed to the spot with a police team.The concerned Twitter blogger also cooperated and said that it was at platform 16 (near Ajmeri Gate) where he had spotted the three children. But the kids were not present when a police team reached the said location. They then started searching all the platforms thoroughly and they were located finally at platform 1 (near Paharganj). It later emerged that the father of the three had left for Kanpur on Tuesday evening. When their mother, identified as Tabassum (37), could not find them for a very long time, she assumed that their father had taken them with him and did not report the matter to the police or even her neighbours. It is possible that the children followed their father, without him being aware of it, and later got stranded.
