There was a report in the Times I think yesterday, which said that whilst Olga and the children were in the refuge after she left US, Olga was witnessed hitting Sara so hard that 'she flew across the room'. Sara and the other children were also taken into care briefly whilst Olga was still with US when one of the children, (I believe it was Olga's son from a previous relationship and was ultimately taken permanently into care) said that he had been assaulted by US and bitten very hard by Olga. She received a caution for biting that child.
Whilst Olga denies most of the claims made by US in relation to Sara, which led to Sara and her brother moving back to US and BB, she admitted that she spanked her once. I also read a report at some point where it was said that Olga admitted that she had difficulties with Sara. That's why I have said previously that whilst Olga may not have been as bad as she was portrayed in the last custody court case -US may well have exaggerated the claims against her - I don't think she was a safe person to look after Sara and her brother either. The children really would have been better off in care.
