The body of a man who was murdered was found stuffed inside a garbage bag outside a Queens home Wednesday, police said.

The grisly discovery was made after a passerby spotted blood leaking from a white bag covered by a blanket on the sidewalk in front of 32-41 104th Street in North Corona just before 2 p.m., according to cops and sources.

Inside the bag, responding officers found the victim with a puncture wound to his back, the NYPD said.

He was pronounced dead on scene.

Police are questioning a man in 30s, who was found with a gun and knife when he was stopped while walking near the scene Wednesday night, sources said.

He had not been charged as of early Thursday morning.
