SPRING, Texas (KTRK) -- A firefighter was hospitalized after a fiercely burning fire caused a three-story building to collapse in south Montgomery County on Monday evening, according to officials.
Deputies with the Montgomery County Sheriff's Office said they responded to a fire in the 25600 block of Interstate 45 at about 7:45 p.m.
Firefighters said the heavy fire was coming out of the second and third stories of the building that was under construction.
Officials said the building completely caved in after about 45 minutes of being on fire. The fire chief noted that it was in the early construction, making the walls lightweight with no exterior walls.
South Montgomery County's Battalion Chief Nathan Huffman said one firefighter was transported to the hospital with minor injuries and is expected to be OK.
Video obtained by ABC13 shows a witness who can be heard saying, "Oh my gosh," while passing the bright fire.
It is unclear what caused the fire. South Montgomery County Fire Department was assisted by The Woodlands Fire Department, Montgomery County Hospital District, and Spring Fire Department.
