SAN JUAN, Puerto Rico - Guards at the Guantanamo Bay prison camp found two prisoners sporting unauthorized underwear, and the U.S. military is investigating to determine how they got the contraband.

Both prisoners were caught wearing Under Armour briefs and one also had on a Speedo bathing suit, items the military said were not issued by Guantanamo personnel or sent through the regular mail, according to a Defense Department letter obtained Friday by The Associated Press.
