The family of three-year-old Anant Gupta, the son of the CEO of Adobe Sytems who was kidnapped on Monday, on Tuesday received a ransom call for his release from captivity.

Though police and the family would not go on record on this, sources said a telephone call was received at the Noida Sector-15 residence of the Guptas on Tuesday morning demanding money for the release of the child.

It was not known how much money was demanded and who were the captors of Anant, who was kidnapped in broad daylight by unidentified persons from outside his house.

Naresh Gupta, father of Anant who returned home from the United States early on Tuesday morning, appealed to the media not to sensationalise the case so that no harm came to his son.

"The more you are covering the incident, it will cause more trouble for our child. My child's life is in danger," an emotional Gupta told reporters outside his residence.

"Please do not cover this issue anymore. We do not have any information about the child. The last time we saw him was at 8:50 am yesterday," Gupta, who is in charge of Adobe's operations in India, said.

Meanwhile, UP Special Task Force teams were dispatched to various places on the basis of clues provided by the maid, other domestic helps and security guards of the area.

Anant was abducted by two motorcycle-borne youths on Monday while he was waiting for his Lotus Valley school bus along with the family's maid outside his residence.
