Tharit Pengdit, director general of the Department of Special Investigation, said Monday that the executives were Piboon Udomsithikul, Wisanu Wisetsing and Jaturong Udomsithikul.
The probe into suspected bidding collusion has been completed and the case would be forwarded to the National Anti-Corruption Commission tomorrow, he said.
Pol Lt Colonel Thawal Mangkhang, a DSI special cases specialist, said the executives would face 20 counts of fraud based on the complaints filed by 20 subcontractors against PCC. Each count would be liable to three years in jail.
The DSI would file another charge of violating the State Procurement Act if police on March 14 decide to cancel PCC’s contract rather than extend the construction period for PCC to complete its job.
If the contract is cancelled, PCC would be accused of entering an abnormally low bid to win the project but then failed to complete the construction.
