EL SERENO, Calif. (KABC) -- More than 140 firefighters battled a massive fire Thursday evening at a warehouse in El Sereno that sent thick plumes of black smoke into the sky over Los Angeles.
The fire at 4900 E. Alhambra Avenue was first reported just after 5 p.m.
Firefighters were able to declare a knockdown in less than two hours. One firefighter suffered an injured shoulder and was brought to a local hospital for treatment.
The Los Angeles Fire Department assigned 146 personnel to the blaze, along with support from the county fire department. Several firefighters were positioned on high ladders above the building using hoses to douse the flames.
The 200-by-200 foot, one-story warehouse building from 2015 to 2018 was used as a roller derby rink by the LA Derby Dolls.
No other injuries were reported and no evacuations were ordered.
The cause of the fire remains under investigation.
