A man was kidnapped at gunpoint and raped by three women who collected his semen in a cool box and stealing it before abandoning their victim - and the method is part of a growing trend.

The 33-year-old man gave the women directions when they pulled up in a black BMW. Suddenly, one of the women armed with a gun got out and forced him into the back of the car at gunpoint.

The trio then drove him 500km away and fondled him in the back of the car but he did not become aroused, so they forced him to drink an 'unknown substance' from a bottle to aid him.

The man was picked up in the Kwazakhele township, Port Elizabeth, and dropped off later, 500km away

They then raped the man repeatedly and collected his semen in plastic bags, placing them in a cooler box.

The man was then kicked out of the car, 500 km away from where they picked him up in the Kwazakhele township, Port Elizabeth, and made off with the stolen sperm.

The exact same method is being used by women in Gauteng, who are also forcing men to drink from a bottle and stealing their semen but no arrests have been made.

Constable Mncedi Mbombo said: 'As he was busy pointing out the directions, one lady came out and pointed a gun at him and forced him into the car,' reports Sowetan Live.

'They drove into a thoroughfare 500km away. They parked the car and fondled him to get an erection but his penis could not get erect.

'They then forced him to drink an unknown substance from a bottle. This got him aroused quickly even though he was still scared and didn't want to have sex.

'This is really confusing to us because we have never heard of such a thing before. The man was fully conscious throughout his ordeal and he is still traumatised.'
