A man has been busted for setting the blaze that killed a Manhattan resident earlier this month, cops said Wednesday morning.

Sadam Assana, 28, was arrested in connection to the fire that broke out around 9:50 a.m. Sept. 4 inside 37-year-old Michael Hannant’s apartment on Ninth Avenue near West 55th Street in Hells Kitchen, cops said.

Once firefighters extinguished the blaze, Hannant was found unconscious and unresponsive inside the home, suffering from smoke inhalation.

He was rushed to NewYork-Presbyterian/Weill Cornell Medical Center, where he died five days later, cops said.

The incident has been deemed a homicide.

Assana, who lives only blocks away, was charged with arson and attempted arson the day of the blaze.

The Manhattan District Attorney’s office would handle any additional charges, cops said.

Assana allegedly set the fire from inside the building, but it was not immediately clear whether he and Hannant knew each other.
