NEWARK — A cargo ship that US authorities thought might be carrying stowaways was expected to leave Port Newark on Friday after a search of more than 160 sealed containers turned up no one.

The ship began its voyage May 30 in the United Arab Emirates, then made one stop in Pakistan and two stops in India. Its last port before Newark was in Egypt on June 15. Federal authorities had said the routing of the ship contributed to the decision to act out of what they described as an abundance of caution.
