Days after 8 SIMI activists were killed in an encounter within hours of their escape from the Bhopal Central Jail, two audio tapes surfaced purportedly detailing conversations between security men involved in the operation, with one saying in Hindi to surround them and finish the job. In the clips, a person can be heard saying firing from the other side has started and asks policemen to take positions. They are told to communicate less on wireless sets and use phones to ensure better communication with police teams reaching the spot. The audio tapes, which come in the wake of video clips that did the rounds within hours of the operation on October 31, raise questions about the official version of the sequence of events. Asked about the audio clips, SP (CID) Anurag Sharma, who is heading the investigation into the operation, did not question the authenticity of the clips, but said he was yet to hear the tapes.
