3.2.9 Inmates claimed that the above-mentioned riot occurred as a result of the HCC's failure to attend to concerns raised, and that, on the day, he had attacked rioting inmates with a hammer. The Area Commissioner was accused of making empty promises. The DCS reported that the first phase of the investigation, headed by the Chief Security Officer (CSO), had been completed, but that statements from those who had been transferred to the super-maximum facility were still being awaited. In February 2012 the region reported that, during a surprise visit conducted by the National Commissioner and the LMN Regional Commissioner earlier that month, new information had been revealed, which would have been included in the final incident report. 3.2.10 On the day of the visit the Regional Commissioner had been provided with a recorded conversation between inmates and the HCC of the Maximum centre which allegedly provided information related to his role in the riot.
