Two more men were jailed 11 weeks each on Friday for commercial sex with an underage Chinese national who was forced into the flesh trade.

Drivers Wu Delong, 35, and Yang Dong, 36, both Chinese nationals, admitted to paying $60 each to the 17-year-old for her sexual services at Min Wah Hotel in Geylang in May. The minor was brought to Singapore by her pimp, Tang Huisheng, 36, who has claimed trial to various vice-related charges, on May 16. They had flown here from Zhuhai, China.

While in Zhuhai, the minor was drugged by her pimp, who had sex with her while she was in a stupor. He repeatedly asked her for sex and if she refused, he would beat her or threaten to do so. She complied out of fear. When she found out that he was going to bring her to Singapore to be a prostitute, she refused and was locked up in a room for more than a week. She injured her waist while trying to escape by jumping from the fifth-floor unit. Both Tang and his sister caught hold of her and beat her up.

The court heard that Wu and Yang had asked the minor for her age and she replied she was 19. But they did not take any other steps to verify her age. So far, 11 others have been jailed between 11 and 12 weeks for similar offences while sentencing on two others, who have been convicted, has been postponed.

The maximum penalty for commercial sex with a person under 18 is seven years and a fine.
