JVP Politburo member Nalin Hewage has called for CCTV footage from the Anuradhapura Prison to be released to media of the incident related to State Minister Lohan Ratwatte threatening a group of inmates.
Hewage said a thorough investigation cannot be expected if the available evidence is not released.
He added efforts are underway to cover up the incident and purposely prolong investigations.
Hewage claimed while CCTV facilities were available at the prison complex, when a senior official is affiliated to an incident, the systems become dysfunctional.
He charged that the truth will be concealed from the public while the State Minister will once again be vested with the same portfolio that he resigned from.
