According to Senior Superintendent of Police (SSP) LR Kumar, the victim, along with her two children, was taken to an under- construction house by a man named Himanshu when she had gone out to purchase medicines on Friday night.
The victim alleged that Himanshu, the son of a policeman, locked her up with the children in the house and left only to return later with two aides to gangrape her, the SSP said.
On Saturday, after being released by the accused, the woman told local residents about her ordeal and went to the police.
On the basis of the victim's statement, a case has been lodged against Himanshu, Khalifa alias Pramod and an unidentified person.
In response to the news of the gang-rape, BJP leader Laxmikant Bajpai flayed the UP government over the dismal security situation in the state, adding, "There is nothing like law and order in Uttar Pradesh, the chief minister isn't capable of maintaining security, and we do not think he will be able to restore peace in the state."
