Four firefighters were recovering Tuesday from injuries they suffered battling a three-alarm fire at a Chula Vista retail store.
The blaze was reported at about 5:40 p.m. Monday at Action Footwear, 655 H Street, just east of Interstate 5, according to the Chula Vista Fire Department.
Investigators believe the fire started on the second floor and was driven by high winds, NBC7 reported. A second alarm was called shortly after crews arrived and was upgraded to a third alarm when the roof collapsed.
Four employees who were inside the building when the fire started reportedly escaped unharmed.
Three firefighters were taken to UC San Diego Medical Center — one for treatment of second-degree burns and two for minor burns — and one firefighter was taken to Sharp Chula Vista for treatment of an ankle injury, according to the news station.
Authorities shut down both directions of H Street from Broadway to I-5.
The cause of the fire was under investigation.
