The investigation into the military crackdowns on red-shirt protesters in 2010 faces delay after new evidence was uncovered, said the National Anti-Corruption Commission (NACC).
NACC spokesman Vicha Mahakhun said the probe is nowhere near completion due to a court inquest unearthing new findings, most notably forensic evidence of those who were killed during the crackdown. The new evidence means the investigation will have to be re-examined, he said.
The NACC's probe focuses on alleged malfeasance involving the now-defunct Centre for the Resolution of the Emergency Situation's (CRES) order to disperse the red shirts.
Mr Vicha is referring to findings from an inquest by the Criminal Court into the deaths of civilians who were killed during the April-May 2010 political violence. Based on the court's findings, which include post-mortem examination reports, some protesters were shot dead by soldiers acting on the orders of the CRES.
In October 2013, the Bangkok South Criminal Court ruled that two United Front for Democracy against Dictatorship protesters killed during the military crackdown in April 2010 were shot by soldiers. The red shirts were Charoon Chaimaen, 46, and Sayam Watanukul, 52.
In August 2013, the same court ruled that soldiers killed six civilians in Wat Pathum Wanaram during the crackdown against red-shirt protesters. The court also ruled in May 2013 that Italian journalist Fabio Polenghi was killed by a bullet fired by security forces during the May 19, 2010, red-shirt dispersal.
Mr Vicha said the NACC expects to review the investigation report early this year.
