The 32-year-old woman, August Elizabeth Thomas, approached Frusciante in 2010, asking to write a screenplay about his life, according to claims filed by the musician in L.A. last week.
"I am worried that she is unstable and that she could snap at any moment," Frusciante said. "I feel like I'm being stalked."
The documents state that Thomas did not take no for an answer and continued to contact Frusciante by email and mail, appearing at concerts where his wife Nicole Turley was performing.
"I fear both for my safety and for my wife's safety. Given that my wife and I are musicians and often play at venues around the world, it is hard for us to avoid Ms. Thomas if she is free to continually show up to harass us," the guitarist explained.
He also alleges that Thomas came to his home on July 28 and 29, which was the final straw before taking legal action.
