A group of people who were on board a ferry from which two people jumped overboard near Harwich have been questioned by police on its arrival in Holland.
Two passengers, believed to be Albanian, remain missing after they jumped from the Stena Britannica shortly after it left port on Wednesday morning.
A ferry passenger told the BBC 's Anna Holligan she saw a group being told that their passports would be handed to police.
