Federal agents boarded an international cruise ship as it docked in Florida before dawn on Friday and arrested one of the world soccer officials who had yet to be captured in a broad corruption investigation, the F.B.I. said.

The official, Héctor Trujillo, the general secretary of the Guatemalan soccer federation who is also a judge on the Constitutional Court of Guatemala, was arrested by federal customs agents. He was expected to appear in a federal courtroom in Florida, said Kelly Langmesser, an F.B.I. spokeswoman.

Mr. Trujillo, 62, was on an island cruise Thursday when the Justice Department announced charges against him and 15 others. Checking the cruise itinerary, federal agents saw that the ship was not scheduled to stop before it arrived in Port Canaveral, Fla.
