At first, fire officials suspected that carbon monoxide or some other toxic fumes had sickened almost 150 people at a Texas bank call center.

It turned out that perfume was to blame.

MedStar ambulance spokeswoman Lara Kohl says 34 people were taken to hospitals, 12 by ambulance, after reporting dizziness and shortness of breath Wednesday at a Bank of America call center in Fort Worth. An additional 110 were treated at the scene.

Fort Worth fire Lt. Kent Worley says the incident started with two people complaining about dizziness after a co-worker sprayed perfume. Others reported being sick when an announcement was made that anyone with similar symptoms should exit the building.

Investigators do not know what type of perfume was sprayed.
