Indonesian prosecutors have sought up to four-and-a-half years in jail for five Thais and three Indonesians accused of human trafficking in connection with slavery in the seafood industry.

The suspects were arrested on the remote island village of Benjina last May after the slavery was revealed by The Associated Press.

In their sentencing demand Friday, the prosecutors sought four-and-a-half year sentences for Thai captain Youngyut Nitiwongchaeron and four countrymen as well as Indonesian Hermanwir Martino. Prosecutors sought three-and-a-half year sentences for two other Indonesians, Yopi Hanorsian and Muklis Ohoitenan.

Prosecutors also demanded the defendants, being tried in Tual, about 2,900 kilometers (1,800 miles) east of Jakarta, pay a fine of about $18,000 or to serve three more months in jail.
