A principal and his teachers were robbed at a school on the West Rand in Gauteng, police said on Saturday.
Two armed men walked into the AB Phokompe High School in Randfontein in broad daylight on Friday afternoon and held up the principal and a teacher in his office.
Sergeant Carmen Hendricks said the men demanded their cellphones, which they handed over, before tying them up with cable ties and telling them not to move.
"The unknown suspects proceeded to the other offices, where they found the other teachers whom they also tied up," she said.
"They took the teachers cellphones, jewellery, money and the school laptops."
The men fled in a grey VW Polo, which was found to have a fake number plate.
