KAMPALA (AFP) – Uganda‘s police warned male bar-goers to keep their noses clean after a probe found a gang of robbers had been using women with chloroform smeared on their chests to knock their victims unconscious.

“They apply this chemical to their chest. We have found victims in an unconscious state,” Criminal Investigations Directorate (CID) spokesman Fred Enanga told AFP.

“You find the person stripped totally naked and everything is taken from him,” he said. “And the victim doesn’t remember anything. He just remembers being in the act of romancing.”

Enanga, who explained that several types of heavy sedatives had been used, said he first came across the practice last year when an apprehended thief named Juliana Mukasa made a clean breast of the matter.

“She is a very dangerous lady,” the official said.

While early investigations suggest that the gang may consist of dozens of members, the source of the sedatives remains unknown.

“We don’t know exactly how they get these materials,” Enanga added. “That is something that our investigations must crack.”

He called on men, particularly traveling businessmen who tend to carry a lot of cash, to take caution.

“It’s a serious situation and people have to be aware.”
