TUAL, Indonesia — Indonesian prosecutors are seeking prison sentences of up to 4 1/2 years for five Thais and three Indonesians accused of human trafficking in connection with slavery in the seafood industry.

The suspects were arrested in the remote island village of Benjina last May after the slavery was revealed by The Associated Press in a report two months earlier.

The victims — 13 fishermen from Myanmar who testified under protection of Indonesia’s Witness and Victim Protection Agency — told the court that they had been tortured, forced to work up to 24 hours a day and were not paid. They also said they were locked up in a prison-like cell in the fishing company’s compound.

In their sentencing demand, prosecutors on Friday sought 4 1/2-year sentences for Thai captain Youngyut Nitiwongchaeron and four countrymen — Boonsom Jaika, Surachai Maneephong, Hatsaphon Phaetjakreng and Somchit Korraneesuk — as well as Indonesian Hermanwir Martino.
