The Crime Suppression Division (CSD) arrested Uthai Songsomphan, 51, in Sadao district on Wednesday night.
Meanwhile, deputy CSD chief Pol Colonel Akkharadej Phimonsri said the seven businessmen would be charged with tax evasion if the information about them evading tax can be proved.
Uthai, also known as Chinnakorn, leads a Phatthalung-based gang that calls itself “Buffalo Racket”, the officer said. CSD will also look into Uthai’s claims that a retired Army general was backing his racket.
