AGUADILLA, Puerto Rico (AP) — U.S. authorities have seized 241 kilograms (about 530 pounds) of cocaine from a makeshift boat traveling toward Puerto Rico's west coast.

U.S. Customs and Border Protection agents said Thursday that after a brief chase, they detained two U.S. citizens aboard the boat and seized 209 bricks of cocaine.

The suspects were identified as Joel Badillo Morales and Carlos Rodriguez Agudo. They were detained late Wednesday.

Puerto Rico is a major drug transit point in the Caribbean.
