Deepti Sarna narrated her ordeal to the police during questioning, where she said that the auto which she boarded from Vaishali Metro station had made a halt near Sahibabad village due to some snag, Senior superintendent of police Dharmendra Singh said.
Later, she boarded another auto in which four men (in their mid-twenties) and a girl were travelling.
The men forcefully offloaded the girl passenger near Hindon river bridge, following which the auto took turn towards Morti village in Raj Nagar extension area, Singh said.
In the midway, they blindfolded Sarna at knife point and thereafter bundled her in a car and ferried her to some unknown place.
After travelling for nearly three hours, the car reached a place where she was kept in a room. The kidnappers never talked in her presence and maintained silence, Singh said.
The girl said that she was not assaulted sexually or physically and was offered food and snacks.
At Friday around 4 am, they dropped her at some unknown railway station platform from where she boarded a Delhi-bound local train.
When the train reached Narela railway station, she asked one of the co-passenger (a senior citizen) to make a call to her parents from his mobile phone.
Police is preparing the sketch of the four men involved in the abduction and they will be nabbed soon.
Due to some glitches in Sarna's abduction story, police is trying to verify the events narrated by her.
"She will also be persuaded to get medically examined at government hospital," SSP Singh said.
Earlier in the day, the girl had called up her family to tell them that she was on a train from Panipat in Haryana.
Suspense remained on the circumstances of Sarna's disappearance, with Superintendent of Police (city) Salman Taj Patil saying that they are investigating the case.
