The abducted three-year-old son of Adobe CEO Naresh Gupta remained untraced on Wednesday, though police claim to have got vital clues which they do not want to reveal at the moment.
"We have managed to develop some information about the people who could be behind the kidnapping. It would not be correct to give any details on the information as it might jeopardise investigations," said Senior Superintendent of Police Rajesh Kumar Singh Rathore.
The boy, Anant Gupta, was abducted by two motorcycle riding men from near his home in Noida while on his way to a bus stop to go to school.
"The complete details of the people involved would be made available at a later stage. We fear the kidnappers might harm the boy if any information about them is revealed," Singh added.
Meanwhile, Delhi Police have also joined the search for the boy given the capital's proximity to the satellite town.
"The kidnappers can try to enter Delhi since Noida is just a few kilometres away. We have started a parallel search for the boy," said Additional Commissioner Crime Branch of Delhi Police Muktesh Chander.
"We are trying to develop information and are in touch with the police of Ghaziabad, Meerut and Muzaffarnagar to further develop clues", Chander said on Tuesday, adding that Delhi Police was the nodal agency to handle inter-state crime in the vicinity of the capital.
The anti-kidnapping cell of the Crime Branch and Special Cell are also assisting the investigations.
With little information on the whereabouts of their child, family members of Anant appealed to the media to not highlight the abduction as the kidnappers could panic and hurt their child. No ransom calls have been received so far.
"Please do not highlight this kidnapping. We have not received any information about Anant," Naresh Gupta told reporters outside his sector 15 A home in Noida.
"We saw him for the last time yesterday and we have not received any information about his whereabouts," Gupta said on Tuesday.
Gupta, who was in the US when the abduction took place, returned to India early on Tuesday.
Gupta, who lived earlier in the US, was posted to India in 1997 to build the Adobe R&D centre.
