Narrative:
Air carrier X was eastbound at FL330 in the north atlantic airspace. Another air carrier X; same call sign; was entering caribbean airspace. Atops does not recognize 2 aircraft with the same call sign. So one of the air carrier X's was removed. But there is no evidence of this happening to the controller in charge of the sector. So to make a long story short; one of the air carrier X was flying with no control. By chance it was discovered by lpaz and we took care of the situation. But it could have been bad (very bad).
