The girl, her "boyfriend" Rajesh, and his friend had set out for Jamshedpur to board a train for Pune on the intervening night of Aug. 27 and 28 when the alleged incident occurred, said SP Saket Kumar Singh.
The girl, a student of class IX, who belongs to Bundu, and the two boys chose to drop in at the residence of her "boyfriend's" uncle near Bundu for a night halt.
The seven accused intercepted them near Kumhara basti in Bundu, thrashed the two boys and chased them away before taking the girl to a secluded place where they allegedly raped her, the SP said.
After she regained consciousness, she narrated her plight to police who launched raids in the surrounding areas and nabbed all the accused yesterday.
"The accused have confessed to the crime during interrogation," the SP said, adding that the girl's actual age was being determined through medical tests to initiate the proper legal process.
The police were also interrogating the girl's "boyfriend", he said.
The girl is recovering at the hospital, he added.
