Ten crew of a Taiwanese fishing vessel, among them a 17-year-old youth, who allegedly mutinied earlier this week, appeared in the Cape Town magistrate's court yesterday.
Magistrate Vusi Mhlangu postponed the case to May 20. He was not asked to grant bail.
Prosecutor Greg Wolmarans said the men were provisionally being charged with two counts of kidnapping.
He told the court there was a great deal of investigation to be done, and that the investigation and the process of gathering statements were made more difficult by the need to use Taiwanese, Indonesian, Chinese and Vietnamese interpreters.
The men, whose names were not made available, were represented by a Cape Town advocate, Alan Goldberg.
A diplomat from the Vietnamese embassy was also in court, while a Vietnamese interpreter translated some of the proceedings for the fishermen.
Members of the police's special task force boarded the fishing vessel, the Balena, before dawn on Tuesday.
Police said 10 of the 29 crew had taken the captain and first officer hostage.
They allegedly commandeered the vessel in international waters at about 3pm on Monday, demanding that it enter Cape Town harbour.
The captain was unharmed while the first officer, who was injured, was treated by paramedics. - Sapa
