A smoky fire in the attic of a medical building on the northeast side this morning prompted a large response, with nearly 100 firefighters arriving at the scene of the two alarm fire, News Radio 1200 WOAI reports.
Firefighters say the fire broke out at Nacogdoches and Leonhardt, which is north of Thousand Oaks.
Officials say two firefighters were treated for heat exhaustion, and the large response was due largely to the hot conditions, requiring firefighters to be rotated in and out.
Nobody was hurt, and the office was not open for business at the time.
The fire was largely contained to the attic, where boxes full of papers were tightly packed.
No word yet on a cause, but it does not appear to be arson.
