An LA County Superior Court Judge ordered 51-year-old Jean Christophe Prudhon to remain at least 100 yards away from the Melancholia actress and her mother at a hearing yesterday (December 9).
Prudhon wrote over 50 letters to Dunst and claimed to have sold his home in order to follow her as she travelled across the world, TMZ reports.
He also admitted to camping outside Dunst's home on ten occasions, and in one letter to the 29-year-old revealed: "[I] came across the oceans five times to try and meet you, always frustrated by fate who took you away each time."
Dunst's mother said in a sworn declaration that Prudhon had confronted her when he turned up on the doorstep of the Spider-Man star's house.
In 2008, Dunst was granted a restraining order against an alleged stalker who broke into her Los Angeles residence.
