A homeless man accused of sparking a massive explosion and fatal fire at a Bronx high-rise told cops he disconnected his ex-girlfriend’s stove from the building’s gas line so he could trade the appliance for crack,

A man was arrested Wednesday for allegedly stealing the stove out of an apartment in the Bronx. He reportedly left the gas on, causing a fiery explosion that killed one person and injured more than a dozen others.

One person was killed and more than a dozen people were hurt when a gas explosion sparked a massive, four-alarm blaze on the top floors of a high-rise apartment building in the Bronx early Saturday morning.

A deadly gas explosion in a New York City high-rise last weekend was traced to an intruder who disconnected a stove to steal and sell it, prosecutors said Thursday.

Samuel Calderon, 55, broke into an ex-girlfriend’s apartment at the Boston Secor Houses, in Baychester, on Jan. 24 and disconnected the stove, then wheeled it down the hall, as seen on video,
