Nguyen Thi Hao, 22, who was arrested by Hanoi police last week for operating a sex ring in the city.
Police in Hanoi on Thursday said they have arrested a 22-year-old woman accused of running a sex ring that targeted wealthy businessmen in the city.
Nguyen Thi Hao was nabbed last week inside a hotel in Bac Tu Liem District, where she arranged for two sex workers to meet their clients.
The sex workers were caught when they were with the two clients, police said, adding that each man paid Hao US$1,000.
The woman said the sex workers received VND5 million ($225) each and she kept the rest.
Hao claimed she started the ring in early June and that she recruited employees at beauty salons and cosmetic shops around the city to work for her.
She then hired a photographer to take pictures of the women and posted them on porn websites and her own Facebook account to lure clients.
Hao added she sometimes did sex work herself when there were many clients.
