The latest news from around North Texas.
The fire department arrived and found ten people reporting nausea symptoms. After the evacuation, five people were treated and taken to area hospitals. There is no word on their conditions.
The McKinney Fire Department checked air quality throughout the building and nothing out of the ordinary was found. Investigators believe the odor may have been linked to work being done on the roof.
A person said to have been in the building reported that "it smelled bad and they were asked to leave." According to this person, roof work had been going on lately.
People had not been able to go back into the building and video showed some leaving in their cars.
