Patong Police were called to the scene, in front of the Central shopping mall on Rat-U-Thit 200 Pi Rd, at about 1:46am.
Officers arrived to find all three suspects still at the scene.
The victim, identified by police as 30-year-old Kuwaiti national Turky Alazemi, had already been taken to Patong Hospital. The extent of his injuries was not reported.
The three suspects arrested were named as Jatuphon Srirak, 37, registered as living in Moo 2, Ratasda; Sayumphu Triranphet, 25, from Songkhla; and Thanakorn Liike, 25, from Nakhon Ratchasima.
The three were taken to Patong Police Station for questioning, Patong Police confirmed.
The investigating officer in the case was given as Pol Lt Col Chayakorn Tangsakul. A copy of the report was sent to Patong Police Chief Col Chalermchai Hirsawat, police noted in a brief report posted online.
Patong Police late this afternoon confirmed that all three motorbike taxi drivers had been charged with causing bodily harm to others.
The end of the assault was recorded on video by a passer-by, still showing Mr Alazemi being kicked repeatedly until he hit the ground.
Police so far have not revealed what caused the assault, though some observers noted it was most likely that Mr Alazemi had parked his motorbike in the area that the motorbike taxi drivers deem to be their domain.
