Coast Guard inspectors called in the cavalry Wednesday at Port Newark, N.J., after hearing the sound of people inside one of the incoming shipping containers. Officials suspect that the container, which was loaded in India and is listed as carrying "machine parts," may be filled with stowaways. (The ship that brought the container originally embarked from Pakistan.) Inspectors "heard sounds coming from one of the containers in the hold consistent with the sounds of people inside," said a Coast Guard spokesman. The dock was swarmed with federal and local officials. According to authorities, stowaways show up at ports in the New York area around six times a year.
