KATY, Texas -

Authorities have evacuated a Cypress-Fairbanks Independent School District middle school for a fire. 

Cy-Fair Volunteer Fire Department officials say the fire was reported around 12 p.m. Wednesday at Thornton Middle School at 19802 Kieth Harrow Boulevard.

Cy-Fair ISD says the school filled with smoke, so the building was evacuated.

Fire officials say the fire started in a wood shop class.

An ambulance was called to the scene to treat a staff member for smoke inhalation.

Officials say firefighters were able to extinguish the fire, but heavy smoke remains in the building.

The middle school students will be bused from Thornton to Cypress Lakes High School, at 5750 Greenhouse Road, where they will stay for the remainder of the day. 

Fire officials say the Ponderosa Fire Department is providing a large fan to assist with ventilation inside the building.

The cause of the fire is under investigation by the Harris County Fire Marshal's Office.
