Katherine Jackson 'tricked' into break

Los Angeles - Katherine Jackson has suggested she was tricked into blocking communication with her grandchildren recently.

Katherine made the claim when she filed a declaration as part of her attempt to obtain co-guardianship over Michael Jackson's children Prince, Paris, and Blanket.

In the documents, she says she was scheduled to go on a road trip to New Mexico to watch her sons in concert - but on 14 July an unnamed doctor showed up to her house and told her it was better for her to take a plane instead.

Katherine says she obliged however when she got off the plane she found herself in Tucson, where she had been set up at a luxury resort.

'I trusted the people I was with'

According to her lawyer: "Her children took her to a spa ... because she had high blood pressure."

When she got to the resort, Katherine says her phone and iPad were taken away and her in-room telephone was disconnected. She also says her TV had sound but no picture so she didn't realise she was reported missing.

Katherine reports: "At the time, I trusted the people I was with to be honest with me."

The declaration contradicts statements Katherine previously made in an interview with ABC News, when she called her sudden absence last month a "short vacation".

During the interview, Katherine said: "One reason I didn't call is I just gave up my phone and I didn't want to have any phone calls while I was here."
