A new device claws an unwanted intruder:

In the event of rape, the device folds itself around the rapist's penis, attaching to the skin with microscopic hooks. It is only when the rapist withdraws that he will realise the device is clamped around his penis.

"Its design will also go a long way towards lowering HIV infection as semen is contained in the device ... as well as preventing sexually transmitted diseases and unwanted pregnancies," Ehlers says.

As it is impossible to remove the device from a penis without medical help, hospitals and clinics will be able to alert police when assistance is sought.
