U.S. authorities say they have arrested seven people after finding 24 pounds (11 kilograms) of cocaine aboard a Royal Caribbean cruise ship just before it was to set off on a cruise from San Juan, Puerto Rico, according to AP. U.S. Customs and Border Protection said Monday that a dog doing cabin inspections aboard the MS Jewel of the Seas found the drugs on Sunday. Royal Caribbean spokeswoman Cynthia Martinez says six of the arrested were U.S. male passengers. The identity of the seventh was not immediately clear. She says the company is cooperating with authorities. The ship departed San Juan on Sunday for an eight-day trip.
