In a fresh twist to the SIMI killings, an audio clip has now emerged in which walkie-talkie conversations, allegedly of police officials, involved in ‘encounter’ with SIMI operatives early this week, can be heard. The authentic of the tape is yet to be confirmed. Eight SIMI activists, who were said to have jumped the Bhopal Central Jail on Diwali night, were killed near Malikheda.
