Opening up about the saga for the first time in a victim impact statement, which was read in court by prosecutor Rita Ali, Keira wrote: "This man has caused me a lot of stress and panic. I am scared every time I go outside. When I return home I have to look behind me concerned, I don't know who might be in the shadows.
"I have had fan mail through the door in the past but never has it been God strange or concerning. The thought of him being on the other side of the door has left me quite shaken."

Knightley, who lives in a $3.1 million (R43 million) five-bedroom North London property with her husband James Righton and their 17-month-old daughter Edie, is even considering moving out of her beloved home because she fears for her family's safety.
"His actions have had a severe impact on my life and the lives of my family," the legal statement continues.
"Since I reported the incident to the police after he meowed through my letter box and had a scuffle with my husband on my doorstep, we are now looking to move house outside the borough.
"We have lived here for two years and my family have enjoyed visiting shops and playing in local parks and being close to the heartbeat of London. My husband and I had hoped our children would go to school here."
