Two firefighters hurt in massive Manhattan electrical blaze

Two firefighters were hurt in a massive electrical blaze inside an Upper Manhattan apartment building late Tuesday, the FDNY said. 

The fire broke out at 7 p.m. in an apartment on the top floor of the six-story building on Post Avenue near Academy Street in Inwood, officials said.

The flames extended into the walls and the cockloft and escalated into a four-alarm blaze by about 8:30 p.m., the department said. It was finally placed under control by about 10:45 p.m.

Two firefighters were taken to North Central Bronx Hospital. 

The FDNY confirmed Wednesday morning that the fire was accidental.

A smoke alarm was present but not activated, officials said.
