The Hornets had agreed a deal for the player who has been in Beijing for the Olympics.
But after he returned to face Queen of the South, McIntyre revealed that the Championship side had changed their minds.
McIntyre said: "The transfer was agreed and for whatever reason only known by them they have decided to pull the plug on it.
"It was very disappointing but we move on.
"Bamba is a good player and he is back in our squad."
