The footage was immediately given to the police, who arrested the nanny after watching what happened. Hoeses has appeared in court and was charged with attempted murder. She was denied bail and will remain in custody until October. She has four children of her own.
Hoeses was hired as a nanny through recommendation by friends of the Theron's, who had previously employed her as a nanny for their two children.
"They feel absolutely terrible now," Mrs Theron said, "they had had no suspicions about her at all, but are now doing their own investigations with the children with the help of a therapist."
