Mr Pramon is also chairman of the board of Toyota Motor Thailand and a board member of Siam Cement Group.
According to the police, the gun attack on Mr Pramon happened at about 3.00 a.m. today at his residence on Soi Prasartsuk off Yen-akart road in Chong Nonsee area of Yannawa district.
Unknown number of gunmen fired over a dozen of shots into the house and then fled.
5-6 bullet remnants were found inside the house. Some furniture inside were damaged by the bullets. However there was no injury.
Mr Pramon was earlier reported to be among major financial supporters of the People’s Democratic Reform Committee (PDRC) listed by the Department of Special Investigation (DSI).
However when some of the names targeted by the DSI was leaked to the media, the DSI then withheld the list and did not announce as it had earlier said.
The list also included Red Bull founder Chaleo Yoovidhya who died on 17 March 2012.
Meanwhile in the attack on the Criminal Court building last night, initial inspection by forensic police suspected it might be an attack by M 79 grenade as two large glass panels were broken.
