Two workers were injured when the floor gave way in a townhouse that was under construction in New Jersey, police said.
The two men fell through the third and second floors of the building in Riverwood Chase and landed on the main level on top of construction debris, officials said.
Initial reports indicate that one of the men landed on some nails, police said.
Both men were taken to nearby hospitals where their conditions are unknown.
Construction officials and police are investigating what caused the floor to collapse.
