The incident occurred on Saturday, Netwerk24 reported. The robbers took cellphones, laptops and jewellery.

In the video below, taken from the family’s CCTV cameras, three balaclava-wearing men with 9mm firearms can be seen getting out of a white Toyota Avanza and running in through the gate.

“The men slipped in when my oldest son closed the electric gate behind some guests,” said Riana Somsen on Sunday. “The three men held up three guests in the driveway who had just arrived.”

“Myself and a friend were in the room near the front door. When I turned around, I looked right into the barrel of the robber’s gun.

“It felt as if time was standing still. He looked for the safe and money. We had to lie on the ground. I told him he should go look in another room.

“When he left the room, I hit the panic button.”

Her children and husband were with other guests at the fire. “I just thought of them.”

Hans Somsen described the scene in an interview with Eyewitness News. He said that one of the robbers entered the room where the children were playing, climbed on top of a table and forced them all to lie down on the floor.

His six-year-old son was one of the youngest people in the house that night.

The robbers stole laptops, cellphones and jewellery.
