More suspects believed to have staged a series of attacks against demonstrators led by the People’s Democratic Reform Committee (PDRC) against the Yingluck government are expected to be apprehended this week, he said.
They were believed to have been involved in several violent incidents in Bangkok, including a bomb attack in front of a major shopping mall in central Bangkok in February this year in which two children were killed, said Gen Somyos.
His remarks were made after police on July 5 arrested a suspect identified as Narongsak Plaiaram in Bangkok’s neighbouring province of Nonthaburi.
Mr Narongsak was suspected of staging grenade attacks on PDRC-led demonstrators in Bangkok.
His arrest was made as soldiers and police confiscated a large amount of war weapons and possessors on order by the National Council for Peace and Order (NCPO) that seized power on May 22.
Gen Somyot said so far police have arrested 15 suspects on threats to national security while nine others remain on the run.
