Ling Yu and Hang Zheng were arrested on charges of engaging in organized crime. They were being held Saturday at the McLennan County jail.
Two other people are accused of helping run the business. The Tribune-Herald reported that authorities issued arrest warrants for Zhao Chen Shi and Xubin Zou, who remained at large on Friday.
Yu and Zou placed online ads for the women while living in New York, authorities told the Tribune Herald.
The other two suspects allegedly arranged for hotel rooms and apartments where the women met their clients.
Officers seized about $115,000 in items — including a Rolex watch worth $38,000 and $20,000 cash — from Zheng’s Houston home.
