A California educator has pleaded not guilty to sexual molestation charges that prosecutors say were filed after a former student confronted her in a phone call and posted the conversation on YouTube.

Andrea Cardosa, a 40-year-old former assistant principal, entered the plea Friday in Riverside County Superior Court.

Judge Helios Hernandez also rejected motions to toss the case and to reduce Cardosa's $5 million bail.

Cardosa was arrested and charged with five felony counts of aggravated assault on a child and 11 other sex-related counts after the allegations surfaced on YouTube in January.

Another alleged victim came forward after the case became public.
