The incident came to light last night when the victim along with her family approached the police.
"The girl was sent to Sanjay Gandhi Memorial Hospital for medical examination. Once rape was established, a complaint was lodged and the duo arrested," said a police official.
As per the girl's statement, her minor relative, who used to frequently visit her house, was sexually assaulting her since the last one week. However, on Wednesday, he called his friend Dharmender who also raped her.
The duo threatened her of dire consequences if she informed anyone about the crime. However, last night she narrated the incident to her family who approached police.
