A fire charred a small building and sent a plume of smoke over Long Beach Boulevard this afternoon—sparking delays on the Metro A (Blue) Line while crews extinguished the blaze.

The flames started at the abandoned building on the boulevard near 23rd Street around 4:30 p.m., Long Beach Fire Department spokesman Jack Crabtree said.

Crews rushed to the scene and had the fire doused within about 10 minutes, Crabtree said.

Video recorded by Jimmy Caivo, who runs LB Fishing Supplies across the street, shows cars passing by the flames clearly visible from Long Beach Boulevard as firefighters arrive.

No one was injured or appeared to be inside the building, according to Crabtree. He said the building was severely damaged by the blaze.

It’s unclear so far what started the fire.
