WASHINGTON (CNN) — U.S. and British military and law enforcement officials are investigating how a man was able to sneak on board the USS Harry S. Truman last month while the aircraft carrier was making a port call in Portsmouth, England.
He apparently was able breach British security at the dock and then board a small ferryboat that carried crew members to the Truman, which was anchored a short distance from the shore.
Navy officials believe the intruder was on board the ship for about half an hour before he was caught. The incident occurred April 9.
Security personnel searched the area where the intruder was caught and found that he had not planted any explosives or caused any damage. It was determined that he was not a terrorist.
British law enforcement officials identified the intruder as Abdoul Masmoud Yessoufou, and told CNN that he also had tried to breach security at British airports and other military facilities.
