Indonesia seized an alleged “slave ship” following a dramatic high seas chase sparked by an Interpol alert after the vessel escaped capture in China and Mozambique, authorities said Tuesday. The boat, captured on Friday around 95km from Weh Island in Aceh province, had 20 Indonesians, two Ukrainians and eight Russians aboard, including the captain, a senior navy official said. The vessel was equipped with some 600 gillnets – banned in some waters – targeting cod species and Antarctic toothfish. Indonesian government has launched a tough crackdown on illegal fishing which involves sinking foreign vessels caught fishing without a permit after impounding the boats and removing the crews. Two years ago, Indonesian warships detained a Chinese trawler wanted by Interpol in Argentina.
