The building is located at the intersection of Detroit and Sixth Streets, just north of Wilshire and west of La Brea. According to the CBS 2/KCAL 9 web site at least 85 firefighers were on the scene with more being called. There are currently no injuries reported.
Along with local media, many onlookers lined Detroit to catch a glimpse of the blaze. What they saw was one of the second-level apartments facing Detroit completely destroyed with the roof gone. There appeared to be another section of the roof that was engulfed in flames that the firefighters were attempting to hose down.
Personal note: I live in older apartment at 3rd and Detroit, less than two blocks away. It is very similar to the one that is currently on fire so I rushed to the scene and thankfully it wasn't mine. My thoughts and prayers are with the residents of this apartment complex who lost everything and now need to rebuild their lives.
