As outrage spread over the horrific gang rape of two Dalit sisters in the district, authorities on Friday sacked two constables in connection with the crime even as police arrested another accused in the case.
The action came three days after the girls were gang-raped and their bodies were found hanging from a tree.
SP Atul Kumar Saxena said the services of two constables Chhatrapal Yadav and Sarvesh Yadav have been terminated.
"One more accused Awadhesh Yadav has been arrested by the police," he said.
Of the seven wanted in the case, three (policeman Sarvesh Yadav and brothers Pappu and Awadhesh Yadav) have been arrested so far, he said.
Sarvesh and Pappu were arrested on Thursday.
Four others Urvesh Yadav (brother of Pappu and Awadhesh), policeman Chhatrapal Yadav and two unidentified persons are at large.
The two girls, who were cousins and 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 the next morning.
The incident had triggered protests in the area with villagers alleging police apathy, following which an FIR was registered against seven persons.
The postmortem report of the two girls confirmed that they were raped before murder, Saxena had said.
Sarvesh and Chhatrpal have been booked under section 120B (criminal conspiracy) of IPC, while the three brothers --Pappu, Awadhesh and Urvesh-- and two others have been booked under Section 302 (murder) and 376 (rape) of IPC.
