Patricia Arquette quits Facebook after alleged cyberstalking

Patricia Arquette has shut down her official Facebook page after claiming that she has been cyberstalked.

The Medium star posted a final message before closing her account on Thursday, revealing that she had been the victim of harassment from a Facebook friend over the last "ten days".

Arquette wrote: "Okay, sweet people - this will be my last facebook post. After my usual not checking email and cell messages for 10 days my security guys chewed me out and let me know why I had to end my 'social experiment'.

"The experiment was, Could a celebrity actually friend strangers and get to know them as a person? Just a regular person? Could you really become friends? Could you move past all that they had in their mind about you and actually show them the real you? Could you get to know the real them a little? I would say on a large part yes. A beautiful and sweet yes... However, apparently 10 days or so that all changed. (sic)"

Arquette also warned her Facebook friends that they should never accept friend requests from people they do not actually know.

"This is important! Just because they were on this page doesn't really mean they are safe! I'm going to say it again because it is important - it doesn't mean they are safe," she said.

Arquette apparently plans to communicate with fans exclusively through her Twitter account in the future.

In July, Arquette and her former husband Thomas Jane finalised the terms of their divorce after five years of marriage.
