“The man instructed her to lie down on the floor,” says Ramphora.
According to the domestic worker the man was in a hurry as he was running.
She managed to press the panic button to set off the alarm.
Ramphora says the suspect was allegedly talking to somebody else but the domestic worker says she cannot remember what he was saying.
“We couldn’t interview her as she was still in shock,” he says.
