Gunmen who fired into the home of Anti-Corruption Organisation of Thailand chairman Pramon Sutivong on Saturday were adept at using a submachine gun never seen in Thailand before, police said.
Cartridges found at the scene were the type used with an Uzi machine gun, Pol Colonel Kittipong Suwan, superintendent of Thung Maha Mek Police, yesterday said.
He said police were scrutinising evidence on Yen Akat Road, where Pramon’s house is located.
The road had many entrances and exits.
Kittipong said witnesses saw two thin and tall men outside Pramon’s home before the attack.
One wore a checked shirt and bought groceries at a nearby shop. Kittipong said the shop owner would remember the man if he saw him again, and police were checking other evidence.
Pramon is also chairman of Toyota Motors Thailand and a director of Siam Cement.
