All the five main accused, including two policemen, have been arrested in connection with the gangrape and murder of two Dalit sisters in Badaun, police said on Saturday.

Constable Chhatrapal Yadav was arrested late last night and Urvesh Yadav was detained in the early hours on Saturday, Superintendent of Police A. K. Saxena told PTI.

All the five accused named in the FIR, including constables Sarvesh Yadav, Chhatrapal Yadav and three brothers Pappu Yadav, Awadhesh Yadav and Urvesh Yadav have been arrested.

The FIR was registered against seven persons including two unnamed men after outrage over the incident.

Taking note of the incident, Katra Sadatganj police outpost in-charge Ram Vilas Yadav was been suspended and two constables — Sarvesh and Chhatrapal — were terminated from services on Friday, Mr. Saxena said.

While the two constables have been booked under Section 120B (criminal conspiracy) of IPC, the three brothers have been booked under Section 302 (murder) and 376 (rape).

The two girls, who were cousins aged 14 and 15, went missing from their house on the night of May 27 and their bodies were found hanging from a mango tree in the village in Ushait area on May 28.

The postmortem report of the two girls confirmed that they were raped before murder.

The father of one of the girls had on Friday called for transferring the case to the CBI alleging that the role of police was “suspicious”.

“The role of police in the entire incident is suspicious. Had the cops acted timely and did not showed laxity, lives of the girls would have been saved. They were hand in gloves with the accused,” father of one of the victim had told PTI.

The Uttar Pradesh government has also sanctioned financial assistance of Rs. 5 lakh each to the family members of the victims while directing officials to provide security to them.
