The incident took place on October 19 when a 14-year-old girl had gone to the field to attend nature's call and a 20-year-old man raped her, police said.
As the girl raised an alarm, the neighbours rushed into the house, caught hold of one of the accused and handed him over to the police, while the other accused was nabbed on Friday.
The girl was allegedly abducted after she went out of her house at Sonapur village on Sunday morning to relieve herself.
Police said one of the accused knew her and called her near the crime scene to celebrate a birthday. Four youths, who were having liquor in a car, forced her to take liquor and she fainted.
The girl was allegedly abducted by two youths staying in her neighbourhood and was raped between March 2 and April 22.
The accused asked the girl's parents to wait as he took her to an isolated area and raped her, police said.
The minor was raped strangulated with a scarf by her tutor Faizul Islam who has been booked under Section 302, 376 and 5/6 of POCSO Act.
A police officer said that the associates of the rape accused might have tried to poison her to stop her from giving testimony in the court. However, it is being verified.
The police said victim's maternal aunt knew about the sexual assault but did not inform the authorities.
