津巴布韦女子团伙为收集精子强暴男性游客

Gangs of women in Zimbabwe have been picking up male travellers to have sexual intercourse and harvest their sperm, according to reports.

Susan Dhliwayo claims she pulled her car over recently to pick up a group of male hitchhikers and they refused to get in, because they feared they were going to be raped.

"Now, men fear women. They said: 'we can't go with you because we don't trust you'," 19-year-old Miss Dhliwayo recounted.

Local media have reported victims of the highway prowlers being drugged, subdued at gun or knife point – even with a live snake in one case – given a sexual stimulant and forced into repeated sex before being dumped on the roadside.

The sperm hunters first surfaced in the local press in 2009 but police have only arrested three women, found with a plastic bag of 31 used condoms in October. The attacks have continued since they were nabbed for allegedly violating 17 men.

"We do not have the exact number of confirmed cases," said national police spokesman Wayne Bvudzijena.

"These cases occurred mostly when the victims were hitchhiking and boarded private vehicles. We encourage people to use public transport."

The sperm's exact use is not clear but is thought to be intended for "juju" or traditional rituals to bring luck – anything from enhancing good fortune, boosting business or preventing a criminal from being detected.

It is also not known why the semen is taken forcibly from strangers.

"It's really an issue which is mind boggling," said University of Zimbabwe sociologist Watch Ruparanganda, who believes it is a lucrative business. "It's quite a big mystery. Obviously we know (it is) being used for rituals."

Ruparanganda said he was astonished to discover seven years ago that semen appeared to have become a tradable commodity, while doing research for his doctoral thesis among Harare street youth who told him that businessmen would take them to hotels, give them new clothes and ply them with booze.

They were then told to pick a prostitute and to hand over the used condom after sex.

"It just shows there's some big racket somewhere, some big guys driving everything, but they are in the background and using these ladies," said Ruparanganda.
