A fire alarm sent students and faculty out of the Peters Building at Fresno State on Wednesday.

Several people stood outside waiting for the alarm to turn off. It rang for about 20 minutes, according to a student who was nearby.

Fresno State Police officers arrived to the building but did not provide a comment about what they found. A Fresno State spokeswoman said the fire alarm had been pulled on accident and that no fire had been reported.

A student who spoke to The Collegian said several faculty stepped out of their classrooms and only some dismissed class. Three students who stood outside the building said they were dismissed from their marketing class just as it started around noon.

The alarm went off the same day a frenzy surrounded English professor Dr. Randa Jarrar, who’s return to campus was highly anticipated after she tweeted anti-Barbara Bush messages in the spring. Her tweets got national attention and the campus has faced a storm of criticism since.

The Collegian has reached out to Jarrar, but she declined to comment on the Twitter controversy or her return.
