The accused, Sandeep, lured the girl to an isolated corner yesterday afternoon while she was playing outside her house in a residential complex here.
The girl started wailing when the youth started molesting her, which drew the attention of the neighbours.
Sandeep, who managed to flee from the spot, was later in the evening arrested at the local bus terminus while trying to escape.
The accused was produced in a local court here today and has been remanded in judicial custody.
