Parents of missing children continue to stream into Nithari village adjoining this industrial township almost two weeks after the serial killings of children and women came to light.
People in the search of their missing children are coming in from as far as Rajasthan, Punjab, Haryana and Bihar.
A control room set up by the local police on Sunday has so far received 273 applications.
"Parents are thronging the camp with the photos of their missing children. We are taking their applications, which will be forwarded to their respective police stations," a senior police official said.
Among the parents is Chandu Chauhan, a resident of Ghaziabad, whose two sons went missing together two years ago and who has since been frantically searching for them .
"My sons were 12 and nine years old respectively. Both went missing on the same day from outside my residence," he said.
Suboth Pal, a resident of Okhla Phase I in South Delhi, was here praying that his teenaged son Rakesh Pal, who went missing 18 months ago, was not among the victims of the grisly killings.
"My son was 18 when he went missing. I have been searching for him ever since," he said.
But the local police are in a state of dilemma as they cannot do much about the complaints.
"What can we do. The parents have already registered FIRs with the respective police stations but they still believe that we would be able to do something for them," he said.
