The accused, identified as Ajay Kumar Roy alias Satrajeet, was arrested after SP, Shillong, requested Delhi police that he be traced and arrested.
The SP had told Delhi police on Tuesday that a man who had kidnapped a five-year-old boy from there on April 19 is using some mobile numbers of Delhi/NCR and may be hiding in southwest Delhi area.

After the marriage, differences surfaced between the accused and his wife. He suspected the character of his wife and they often had quarrels due to this.
