Santi Pawai, chief tourism and sports office of Phuket, led tourist police, and officials from other agencies to check the nine firms in Phuket’s Muang district.
The firms included Five Stars Sea Cruises Co Ltd, Amazing Bike Tour Co Ltd, and Dive Marine Co Ltd.
Following the inspections, Santi said all the firms failed to provide documents to identify the owners. They were given five days to provide proper documents or they would face a fine of Bt4,000.
