The statement was recorded from journalist Kasun Pussewela after he had filed a petition at the HRCSL.
Pussewela had sought an investigation into the incident saying there was ample evidence to prosecute some people who were responsible for killing prisoners who took part in the riot.
The HRCSL obtained written evidence from Pussewela today as well as video and photographic evidence.
The riot broke out during a search for illegal arms and it left 27 people dead and 40 injured.
The Government had appointed a committee to investigate the riot and a report was compiled on the incident but it was not made public. (Colombo Gazette)
