Los Angeles ( CNN ) -- Security camera video obtained by CNN shows the tension between Jackson family members amid a very public dispute over the whereabouts of Katherine Jackson . The 82-year-old matriarch of the Jackson music dynasty has not contacted Michael Jackson 's three children since she left the home she shares with them on July 15 , although a sheriff 's investigation concluded she is safe in Arizona . Siblings Janet , Jermaine and Randy Jackson attempted to convince Michael Jackson 's two oldest children to leave Katherine Jackson 's home with them Monday , but Paris and Prince resisted , three sources with knowledge of the incident said .

'' Prince , 15 , is seen walking away from his Uncle Randy into the home 's security office . Paris soon followed .

No one was arrested , although a battery report was taken and an investigation is ongoing , Los Angeles County sheriff 's spokesman Steve Whitmore said . The drama happened as Los Angeles County sheriff 's detectives closed a missing persons case opened for Katherine Jackson , who was found to be with her daughter Rebbie in Arizona . `` Katherine Jackson has been located and she is fine and with family , '' Whitmore said . `` Our missing persons case is closed . '' Deputies talked to two family members and were satisfied , he explained . A lawyer for Katherine Jackson , however , was not satisfied , saying the sheriff 's deputies who tried to talk to her in Arizona Monday were blocked from seeing her . Because she was taken across state lines , Katherine Jackson attorney Sandra Ribera said she hopes the FBI will investigate . Jermaine Jackson , in a statement posted on Twitter Sunday night , said his mother `` is safe and well in Arizona with her daughter and our sister , Rebbie , resting up on doctor 's advice . '' But Michael Jackson 's three children still have not heard from their grandmother , eight days after she left them at home , Ribera said . `` 8 days and counting . something is really off , this is n't like her at all .. i wan na talk directly to my grandmother ! ! < |3 '' Paris tweeted Monday . Jermaine Jackson 's statement insisted the children were not `` being 'blocked ' from speaking with Mother . '' `` She is merely an 82-year-old woman following doctor 's orders to rest up and de-stress , away from phones and computers , '' he tweeted . His statement did not explain why Paris was rebuffed during several attempts to reach her grandmother on the phone . It is the latest chapter in a messy dispute between several of Jackson 's children and her advisers . Whitmore confirmed that the sheriff 's department is investigating allegations that Jackson was being `` emotionally and financially mistreated by family members .

The abuse probe began when `` a business associate of the Jackson family '' reported the allegation to a sheriff 's official in April , Whitmore said . `` Investigators contacted Katherine Jackson and she emphatically denied any and all of ( the allegations ) , '' Whitmore said . When investigators met with Jackson , she was `` in good health and voiced no complaints , '' he said . `` Out of an abundance of caution , we have continued to interview legal representatives of the family about the possibility of financial abuses , '' he said . `` That investigation remains open . '' Katherine Jackson 's lawyer and business manager declined to comment .
