The National Human Rights Commission (NHRC) has issued notices to Tamil Nadu director general of police (DGP), Chennai district magistrate (DM) and senior superintendent of police (SSP) seeking details of the recent encounter in the city wherein five alleged bank robbers were killed.

The panel has sought a copy of magisterial inquiry report and post-mortem examination reports of the deceased.

Meanwhile, a PIL has also been moved in the Madras High court seeking a probe by the Central Bureau of Investigation (CBI) into the incident.

The city police had claimed that the encounter took place after the suspects fired at a raid party injuring two police inspectors. However, doubts were raised on whether it was a genuine encounter.

Headlines Today tracked down one of the suspected robbers, who had been taken as killed in the encounter that took place in the wee hours on Thursday, in Bihar. He was found to be alive.

Headlines Today reached the residence of Chandrika Rai in Fatuha area of capital Patna and was shocked to actually find him alive. Now the question rises who was the deceased who had been identified by the police as Rai.

Rai told Headlines Today that he earned his living by driving a truck. He said there was nobody else by his name in his village Maujipur.

In Howrah, the landlord of another suspect killed in the encounter -- Abhay Kumar -- told Headlines Today that no person lived in his house by that name. The house owner, Mohammad Aslam, said he has been living in the house for 35-40 years.

Even the explanation given by the Chennai Police has also raised eyebrows. The police said they had given out names and addresses of victims based on voters' identity cards found from the house where the encounter took place.

The police had said the robbers were behind two heists within a month and that four of the suspects were from Bihar and one from West Bengal. They had claimed that the deceased had looted Rs 33 lakh from two banks in the city's suburbs.

Police had identified the deceased as Vinod Kumar, Chandrika Rai, Harish Kumar, Vinay and Abhay Kumar. They were all aged around 30 and 35 years.

Acting on a tip-off from a person, who had seen the CCTV camera grab of one of the suspects released on Wednesday, a 14-member police team had raided a Tamil Nadu Housing Board Colony apartment on Netaji Street in Velachery around 1 am on Thursday. The police claimed as soon as the suspects saw them they started firing from the windows and refused to respond to calls to surrender. The police then broke open the door and returned fire thereby killing all the five suspects, they claimed.
