DSI Director-General Tharit Pengdit said the DSI has already sent additional information concerning the GT200 case to the National Anti-Corruption Commission (NACC).
According to Mr Tharit, 13 agencies, which were conspiring during the acquisition of the devices, will be called in within two weeks to hear the charges.
The British-made GT200 bomb detecting devices were acquired over two years ago at around 1 million baht each, but test results showed they were ineffective at scanning for explosives.
The test result, conducted by the National Electronics and Computer Technology Center (NECTEC), will be part of the evidence in the investigation.
