Johannesburg - The nanny of a 14-month-old toddler who was kidnapped during a house robbery in Soweto earlier this week is suspected of being involved in the crime, police revealed on Friday. General Fred Kekane said baby boy Siyabonga Mlambo was found in Newcastle after an extensive search by police.Kekane said a task team investigating the kidnapping had found loopholes in the nanny's story. "We could see something is not clear with the nanny. After further investigation, [an] instruction was given to detain the nanny."Kekane said the nanny, who was also a cousin to the Siyabonga's mother Mandisa, and her two alleged accomplices had also been arrested. The two alleged accomplices were related to the nanny. One of the men was a sangoma.
