Speaking on GMTV, La Toya said the family was not comfortable with people who surrounded her brother.
She told the ITV show: “Michael was in a position where [he was] very meek and very kind and people would just barge their way into his life and into his circle which was not a good thing to do.
“People controlled him. They controlled him, they did what they wanted.”
La Toya also said of the investigation into her brother’s death: “I think that they’re doing an absolutely wonderful job.”
