The accused, who had come here by a train from Delhi, was traced after tracking his mobile phone location, police sources said.
Kumar had married recently and his wife had come to her parent's place two days back.
The accused, working as labourer in Delhi, is a native of Bharphua village of the district.
Kumar allegedly raped five-year-old girl at his rented accommodation in east Delhi's Gandhi Nagar. The girl and her family stayed in the same building where Kumar lived.
Delhi police have registered a case and slapped charges of attempt to murder and rape among other things on Kumar, who allegedly confined the girl in his room for at least two days.
The girl, who was reported missing from April 15 evening, was rescued on April 17 morning from the ground floor of the building.
The girl is battling for life in AIIMS hospital in the national capital after she contracted infection from foreign objects inserted into her body.
