Patricia Cornwell, crime writer, claims that a cyberstalker is causing her anxiety, fear and sleeplessness. 

She claims that Leslie R Sachs has been posting defamatory messages about her on the internet, including accusations that she is a "Jew-hater" and has asked the court to make him stop.
The cyberstalking case is part of an ongoing libel lawsuit that Cornwell has against Sachs, who calls himself a "political refugee", who has moved to Europe to escape Cornwell's lawsuit.
