The deadly incident happened around 10:30 p.m. on Saturday inside a building on Bedford Avenue in Crown Heights.
Three officers in Bergen County, New Jersey went beyond the call of duty to help an elderly resident, police said on Tuesday.
Despite the overwhelming smoke and heat, one of the responding officers crawled through the back of the home to find the woman.
The man who allegedly pushed an elderly woman onto the subway tracks in Flushing, Queens has been taken into police custody.
Police have arrested the man they say sucker punched an 81-year-old woman in a random attack on the Upper West Side last month.
Both attacks happened on Friday, September 13, and appear to be unrelated, but occurred within just hours of each other.
