An Illinois insurance executive has pleaded not guilty in Los Angeles to secretly making nude videos of ESPN reporter Erin Andrews.

Michael Barrett entered the plea Monday in federal court to one count of interstate stalking.

The 48-year-old Barrett remains free after posting a higher-than-expected bond Friday of $100,000. Judge U.S. Magistrate Judge Carolyn Turchin set the amount after Andrews' attorney called Barrett's alleged behavior calculated, cunning and secretive and said he posed a threat to the public.

Prosecutors say Barrett found hotels where Andrews was staying three times last year. They say he rented an adjacent room, altered the peephole and shot videos of Andrews.
