Her filing states that Zachary Loring, 24, first appeared at her home on Aug. 26 and came back over the next several days. Patridge's filings and jail records show Loring was arrested on Aug. 30 and released a day later.
Loring gave Patridge a packet of letters and drawings, including one that showed a woman being strangled when he first went to her home, the court filing states. He appeared three days later and was captured on surveillance footage, according to the documents.
Loring was arrested after Patridge saw him outside her home on Aug. 30. Jail records do not indicate if he has an attorney and a phone number could not be immediately located.
"Ms. Patridge is in great fear of returning to her home and is currently staying outside of Los Angeles County due to her fear for her personal and physical safety," her attorney wrote in the restraining order petition.
The order requires Loring to remain 100 yards away from Patridge and her younger brother, Mark and to not try to contact either of them.
A hearing on a three-year restraining order is scheduled for Sept. 30.
Patridge also appears in the horror film "Sorority Row," which opens in theaters on Friday.
The filing was first reported by celebrity Web site TMZ.
