Kiri Kanchanapas and Surapong Laoha-anya, the top executives from the Bangkok Mass Transit System PLC (BTSC) acknowledged additional allegations at the Department of Special Investigation (DSI) but flatly turned down that any wrongdoing had occurred.

The DSI charged them with illegally signing an agreement with the Bangkok Metropolitan Administration (BMA) to operate the extended sections of two mass transit routes: the Silom Line from Taksin to Wong Wien Yai stations and the Sukhumvit Line from Bangchak to Bearing stations.

The BTSC is a private company invited by the BMA to jointly manage the Skytrain service and the company would never intend to breach the law, they said.

The DSI has yet to decide if it will submit the case to the Attorney General for further legal action. The BMA executives including Bangkok Governor Sukhumbhand Paribatr have been separately charged by the DSI in connection with the case.
