A Vietnamese-Chinese woman was among four Vietnamese arrested by Taiwanese authorities during a special operation on Monday to combat vice activities in an eatery in Kaohsiung City, southern Taiwan.

Acting upon a tip-off, officers from the National Immigration Agency placed under observation a restaurant in Daliao District in Kaohsiung City. According to the tip-off, the restaurant allegedly housed Vietnamese women who would travel to the island country on tourist visas to offer sexual services, The Real Daily reported.

After keeping the restaurant under surveillance for several nights, on November 19 immigration officers together with Linyuan police raided the eatery. There, they arrested four Vietnamese women for allegedly breaching their conditions of stay by working as hostesses in sexy outfits and plying customers with alcoholic drinks.

Preliminary investigations suggest that the hostesses also offered illegal sexual services to customers.

Among the arrestees was a student who allegedly worked part-time so as to cover her university fees and living expenses in Taiwan. Her arrest means she is in danger of having her scholarship taken away and being expelled by her school.
