A fire at a downtown Los Angeles warehouse that sent flames 100 feet in the air has been extinguished.

Fire Department spokeswoman Melissa Kelley says the blaze at Yoni Distribution was reported at 4:33 a.m. It took 150 firefighters about two hours to douse it.

Smoke and flame were visible for miles and part of the 100-by-150-foot building collapsed.

The warehouse contained car audio equipment and car alarms. Kelley says there probably was significant smoke and water damage, but she didn't have a dollar figure.

No injuries were reported and the cause of the fire hasn't been determined.
