Firefighters battle blaze at Eagle Rock apartment building for two hours before extinguishing flames

It took over 100 firefighters to extinguish a fire that broke out at an under construction apartment building in Eagle Rock on Saturday. 

The fire was first reported just after 3 a.m in the 150 block of Chia Way, according to the Los Angeles Fire Department. 

Crews arrived at the scene and found large flames that had engulfed part of the four-story building. At it's peak, there were about 140 firefighters on scene battling the blaze and working to prevent it from spreading to nearby structures. 

Almost all of the work was done from outside of the building due to the potential danger being posed to firefighters, the department statement said. 

After just over two hours the fire was finally reported extinguished by crews. 

The cause of the blaze remains under investigation. 

No injuries were reported. 

Video from the scene shows massive flames shooting from the top of the building.
