The incident, which occurred at Ban Bang Rong on Wednesday night (July 31), was made public by video posted online by Facebook user Teen Night.
The video, nearly four minutes long, explained that the man was surrounded by young men and confronted at 10:45pm.
A woman was also present, who explained that the man had been caught secretly watching her daughter take a shower.
After being spotted by the mother, who shouted for help, the man had fled. The group of young men pursued him and confronted him while his motorbike lay on the ground.
The man repeatedly denied he had spied on the daughter, and repeatedly asked the young men to calm down.
He told the men that he was riding home from seeing friends in Muaeng Mai to where he was staying in Kamala, a long way and a different direction from where he was caught.
At first the man said he had stopped to fill up his water bottle, and later said that said he had stopped to urinate.
While being confronted, one of the young men elbowed the man in the neck. Another man punched the accused in the head. Still the man did not flee, and repeatedly called for the men to calm down.
The man eventually did flee after another young man behind him landed a flying kick to the side of his head, and continued his attack.
Another video of the incident posted online showed police arriving at the scene.
In the compartment under the motorbike seat of the man who had fled were women’s panties, condoms, a small jar of vaseline and a cucumber.
One of the posts online said that police were investigating the incident further and were working to track down the man.
Among the items under the motorbike seat was the man’s wallet, including identification cards.
