Patricia Arquette shuts down Facebook account

Patricia Arquette is shutting down her Facebook.com page after reportedly becoming the target of an Internet stalker.

The 43-year-old True Romance star invited strangers to contact her via Facebook as part of a "social experiment" but one man has left her fearing for her safety.

In a final post, Patricia Arquette told her 2,900 Facebook friends not to "friend anyone here that you don't personally know." She added, "This is important! Just because they were on this page doesn't really mean they are safe!"

Patricia Arquette has insisted she will keep in touch with her friends via Twitter.com and thanked fans for sharing their "love, humor and sadness" with her.
