The 18-month-old boy, who was kidnapped allegedly by a domestic help from his Delhi home three days ago, has been rescued from neighbouring Faridabad with arrest of four persons, including two women, police said on Wednesday.

Ishaan, the son of a prominent businessman was kidnapped allegedly by maid Seema from Southeast Delhi’s Maharani Bagh on Sunday evening after she took him for an evening walk. The maid was employed by the family 10 days ago without police verification.

The boy was rescued from Faridabad, near badarpur border around midnight, a senior police official said.

“We have rescued the boy and arrested four persons, including two women. One of the two women arrested is the maid,” the official said.

Two of the accused belong to Orissa, while one each are from Bihar and West bengal.

“The kidnapping was pre-planned. All the four accused knew each other and their motive was to become rich quickly,” he said.

Earlier, police had said it appeared that the maid had kidnapped the boy due to fondness for the boy.

Delhi Police had formed 15 teams, including one from Crime Branch, and send them various parts of the country in search of the boy.

Delhi Police had declared a reward of Rs. 50,000 for anyone providing information about the child and released the sketch of the suspect. The police had also released a second photograph of the victim on Tuesday.

A case under Section 363 (kidnapping) of Indian Penal Code was registered. If convicted, one can be punished with imprisonment for a term which may extend to seven years and shall also be liable to fine.

According to Delhi Police, 551 children have gone missing from the capital this year, with this month alone accounting for 176 such cases.
