Pattaya police rounded up 50 sex workers from Beach Road on Tuesday ahead of the international boat show next week.
77jowo reported that the women were aged between 18 and 45 and were selling sex.
Their names were taken and they were given warnings.
Billed as a crime prevention and image measure, the news media said the sex workers were rounded up as they could cause annoyance to the thousands of visitors expected in Pattaya for the show.
The move was also carried out to prevent crime such as snatch theft.
Representatives from 38 countries are expected at the Ocean Marina Pattaya Boat Show 2017 with some 6,000 visitors expected to flock to the city.
77jowo referred to the women as “phee maphraw” (coconut ghosts) in their headline. The women habitually wait for customers along the tree lined walkway.
