Justice Minister Suwaphan Tanyuwattana said the DSI chief has notified him of the transfer of the case from the police to the DSI after a M16 assault rifle seized during the police searching of places in seven provinces with link to Ko Tee was among the seized weapons.
The assault rifle was linked to a terrorism case in 2010, he said.
Meanwhile Deputy National Police Chief Srivara Rangsibrahmanakul said police have questioned the arrested nine men in connection with the arms seizure last week.
All confessed to be members of Ko Tee’s network and all firearms and ammunition were gathered by Ko Tee.
They were kept since the anti-government protest in 2010.
The weapons were moving into the house recently. Some of the seized weapons had been taken from soldiers during the violent red-shirt political rallies in mid-town Bangkok in 2010.
Pol Gen Srivara also denied the seizure was set up by the government as some of the weapons were not used by the armed forces or police.
He added that the military intelligence has found the movement of Ko Tee’s network at Klong Luang market in Pathum Thani during the operation of the Department of Special Investigation (DSI) to search Wat Dhammakaya to find Phra Dhammachayo.
Royal Thai Police deputy spokesman Pol Col Krissna Pattanacharoen said police have substantial to prove that the weapons cache seized was meant for the attempt to assassinate the prime minister and his deputy.
He said the national police chief has ordered the police to find the source of the weapons and the linking of the group who give the financial support to the group.
