This comes after they ambushed a couple near the Hennops River on March 10 last year.
“The accused hijacked the couple‚ kidnapped‚ robbed [them] and raped the female victim.”
The fourth suspect‚ 25‚ was arrested in Limpopo.
“He faces charges of convicted criminals plus murder he committed with [a] firearm robbed from the victims.”
He will appear in the Pretoria magistrate’s court on Monday.
