A Roman Catholic priest in Puerto Rico has pleaded guilty to transporting a minor with the intent to engage in criminal sexual conduct.

Israel Berrios was arrested in May amid accusations that he sexually abused an altar boy from the time he was about 8 years old until he turned 17.

Authorities accused Berrios of giving the boy money, a computer and a camera and taking him on a four-day cruise to the Bahamas with his mother's permission in July 2008. The boy was 15 at the time.

Berrios is the first priest to face federal sex charges of that kind in the U.S. territory.

The U.S. Attorney's Office said Thursday that Berrios could face up to 12 years in prison.
