Jaspreet Singh, a resident of Sadhawali village, was arrested for allegedly abducting the girl and then repeatedly raping her for four days in a room in Hoshiarpur, SHO Sukhdev Singh told reporters.
Two of Jaspreet's accomplices -- his relative Vicky and an unidentified youth -- are still absconding, he added.
The girl, who is studying engineering at Mohali, had come to her village during vacations.
On March 10, she was standing outside her house when Jaspreet, who had earlier proposed to marry her, forcibly took her in a car to Hoshiarpur and raped her there.
