Patrol officers on Wirat Hongyok Rd in Vichit saw the woman, Feng Ying, 34, haggling with Chinese tourists in front of Lanna Traditional Thai Massage at 2:15 am yesterday (Sept 3).
The officers intervened and asked to speak with their tour guide, but no one came forward.
Police then questioned the 26 tourists and they pointed to Ms Feng, who was found to be holding tour brochures and vouchers for tour company Yongler International Travel Co Ltd.
“Feng Ying did not have a work permit or tour guide license,” said Maj Krisathorn Uthong of the Tourist Police.
“She said she had been working as a tour guide with Yongler international Travel Co for four years and was paid on commissions.”
Feng was taken to the Tourist Police headquarters in Phuket Town, where she was charged with working illegally in Thailand on a temporary visa and working illegally as a tour guide.
