A gang of robbers hit a school guard with a hammer before gang-raping his wife in their home on the school grounds in Etwatwa yesterday, East Rand police said.
The couple were sleeping when the five robbers burst into their house, said Inspector Juanita Killian.
After attacking the couple, the robbers took computer equipment from the school.
"The equipment was, however, recovered when three of the men were caught on the school premises," said Killian.
They will face charges of housebreaking, rape and possession of stolen property.
"Police are on the lookout for the two remaining men," she said. - Sapa
