LOS ANGELES - Kirsten Dunst doesn't need Spider-Man -- she's got an assistant who recently proved capable of protecting the actress.

Dunst's assistant performed a citizen's arrest on a man who bypassed security and showed up at the actress' Hollywood home in November. Dunst was not home at the time. Police and Dunst sought a restraining order against Christopher Smith after his Nov. 20 arrest.

Documents show state police have found Smith at Dunst's home several times in recent weeks.

The actress wrote she is "quite frightened" of Smith, whom she has never met.

Smith is due in court later this month on a trespassing charge. Dunst's restraining order could be extended on December 22.
