Man critically injured, dogs rescued in LA house explosion linked to fireworks

LOS ANGELES - A Pacoima neighborhood was rocked by a blast so powerful it blew the roof off a home and left a man with severe burns. 

Investigators said the explosion was triggered by fireworks. 

What we know:

Firefighters with the Los Angeles Fire Department were called to a home located in the 13550 block of W. Remington Street in Pacoima, located near the intersection of Terra Bella Street and Laurel Canyon Boulevard, just after 9 a.m. Thursday. 

A 24-year-old man was pulled from the house. He was rushed to an area hospital in critical condition with severe burn injuries. 

Video shared with FOX 11 showed people running to his aid. Witnesses say he told them there were additional fireworks in the house. 

He also told authorities there were pets inside.

Three of the four dogs were rescued. However, one of them remained trapped in the rubble as their leash appeared to be tied to a refrigerator. Around 5 p.m., officials said all four dogs were safe and rescued. 

A crew with SoCal Gas was also at the scene. 

What we don't know:

The ATF has been brought in to help with the investigation. 

While police confirmed the explosion was linked to fireworks, the exact cause is still under investigation. 

While searching the home, investigators found several other fireworks. 

"I don't know that they were being manufactured, but that's just what we believe now because of the remnants that were behind," said LAPD Lt. Al Orozco. 

Several neighbors told FOX 11 they've been calling 911 because of fireworks in the area, even hearing some last night.
