An Irish teenager who stowed away on a Navy destroyer with the help of sailors was hospitalized Wednesday after she apparently went into convulsions while being taken to a return flight to Ireland, officials said.

Five sailors accused of helping the girl cross the Atlantic aboard the USS Conyngham remained in custody, the Navy said.The girl, who Navy officials said is 16 years old and who Irish officials said is 15, was found Saturday evening aboard the guided missile destroyer when it arrived after a 10-day cruise from Cobh, Ireland.

She was being flown Tuesday from Washington to Atlanta for a flight to Ireland when she became ill.
