The guy who played Detective David Starsky on the '70s classic "Starsky and Hutch" claims he's living in fear of an "irrational" female superfan who's been lurking around his apartment -- and he needs protection STAT!
TMZ has obtained documents filed by Paul Michael Glaser -- in which the actor begs a judge to slap a restraining order against the woman who used to run his official website.
In the docs, filed last week in L.A. County Superior Court, 68-year-old Paul claims the woman is so obsessed with him -- she followed him to England three years ago to watch him perform in a play ... a play she attended 23 TIMES!
Paul also claims she's fired off more than 500 emails to him over the past two years in which she exhibits "both a rational and very irrational side."
Glaser adds, "I am about to start a tour with my book, and given [the woman's] behavior, I fear for my safety."
Glaser wants the judge to make sure the woman stays at least 200 yards away from himself and his family.
