New Delhi: Families of the four rape and murder accused, who were killed in an encounter in Telangana, filed a petition in the Supreme Court seeking registration of FIR, investigation and criminal action against police personnel, who were involved.

The veterinarian was gang-raped and killed by four people before they burnt her body in Telangana's Shamshabad on November 27. Her charred body was recovered a day later.

A few days later, the accused persons were killed in a police encounter. Family of accused -- Jollu Lakshmi, mother of Jollu Naveen, Jollu Rajaya, father of Jollu Siva, Chinthakuntla Kurmanna, father of Chinthakuntla Chennakesavulu and Pinjari Hussain, father of Ahmed, have approached the apex court, seeking directions and relief from it.

They sought to quash the FIR registered by the police against the deceased in which police claimed that they had attempted to murder police personnel prior to the encounter.

The petitioners were represented by lawyers PV Krishnamacharya and R Sathish.

They have also sought a direction for adequate compensation of Rs 50 lakh for each family for extrajudicial killings and custodial death of their sons.

"All the four alleged they are innocent. The respondent, the police, have killed these four accused in a fake encounter only to please the public, while destroying the evidence to protect the real culprit as the police have failed to track the real culprit," the petition claimed.

The petitioners claimed that there is 'no clear or direct evidence to link them with rape and murder.

The petitioners sought directions to restrain the police officials including CV Sajjanar, commissioner of police, Cyberabad, and Telangana state government from tampering with evidence, intervening into the case of encounter killing and influencing the witnesses.

The top court had last week ordered setting up of a three-member inquiry commission to probe the encounter case and stayed proceeding before Telangana high court and National Human Rights Commission (NHRC) until further orders.

The panel will be headed by a former apex court judge VS Sirpurkar and comprises former Bombay high court judge Rekha S Baldota and former CBI director DR Karthikeyan.
