The police, along with port administration personnel aboard rubber boats, also ordered a Greenpeace activist to get off the Gran Couva tanker.

The activist, identified as Adon, had tied himself to the chain of the anchor of the Gran Couva owned by the Wilmar Group to protest the CPO shipment bound for Rotterdam, the Netherlands.

Adon and his companion, Bustar Maitar from Forest Campaigner Greenpeace Southeast Asia, were questioned by the police, but not detained.

The police also ordered the MV Esperanza Greenpeace vessel to leave Dumai port as its berthing period had expired.

Maitar said the Greenpeace believed that the expansion of oil palm plantations had contributed to the destruction of peat moss and natural forests of Indonesia.

"Ironically companies like Wilmar and Sinar Mas are members of RSPO (Roundtable on Sustainable Palm Oil Supply). So long as no public statement has been made by the RSPO that supports a moratorium on the deforestation eco-friendly oil palm plantations are a myth," he said.

He said the Esperanza would stay in Dumai waters to monitor forest conditions in Riau. (PNA/Antara)
