Search for stowaways comes up empty on New Jersey cargo ship

U.S. authorities have not uncovered any stowaways after an extensive search of a cargo ship docked in New Jersey.

The search began Wednesday after a Coast Guard inspection team heard knocking for about two hours from a container.

The Department of Homeland Security says officials examined 450 out of 2,000 containers.

The ship began its voyage May 30 in the United Arab Emirates. It made one stop in Pakistan and two stops in India. Its last port before Newark was in Egypt on June 15.

More than a dozen ambulances and law enforcement officials met the ship when it docked Wednesday at Port Newark, one of the nation's busiest ports.
