The investigation is in response to a request submitted to the DSI by Pheu Thai Party spokesman Prompong Nopparit against the Democrat-led city government.
Prompong alleges there was corruption and bidrigging involved with the construction of the giant tunnel and drainage tunnels at Sukhumvit Soi 26, Khlong Prem Prachakorn, Phaya Thai, Sukhumvit Soi 36, Sukhumvit Soi 42 and Bung Makkasan.
