The youth was named in the FIR by the victim's parents. She had been missing since last Tuesday after she left home for tuition classes. Her body was found half-naked near a canal, 100 kms from her home in Jind.
On January 13, three men in Faridabad abducted a 22-year-old woman when she was returning home after work and gangraped her in a moving auto for several hours.
Police claimed no injury marks were found on the body, adding that postmortem was underway.
The 15-year-old 12th Class Dalit girl was brutally raped and murdered in Haryana's Jind district.
The two men arrested both reportedly confessed to luring the girl to their house before raping and killing her, the police chief revealed.
The girl was brutally assaulted, her private parts mutilated and some of the vital organs ruptured, the police had said. Haryana becomes the scariest for girls in four days because the city had reported around eight rape cases. A UN Committee on the Rights of the Child in 2014 said one in three rape victims in India was a minor and expressed alarm over the widespread sexual abuse of children.
The role of the police, he continued, was to "investigate, catch criminals and prove things" and "we're leaving no stone unturned".
The girl's family has denied any links between their daughter and the boy, but police sources said cellphone call details showed the two had been in touch.
In his first response to five rapes in five days in Haryana, chief minister ML Khattar on Wednesday termed the incidents as "unfortunate" and said his government will take strict action.
Another case of rape of a minor has come to light in Haryana's Hisar district. "Such heinous crimes are increasing, but the government seems to be in slumber". A Congress delegation, led by former CM Bhupinder Singh Hooda and comprising senior leaders including Kumari Selja, state CLP leader Kiran Choudhary and Mahila Congress's national president Sushmita Dev met the Haryana Governor Kaptan Singh Solanki today and apprised him about the deteriorating law and order situation in the state.
