The three Dutch are Erhard Leffers and Marianne Vos, who work for a printing and publishing company in Dedemsvaart, Netherlands and a documentary filmmaker, Jandries Groenendijk.
The trios were seized in Letugbene waterfront in Ekeremor Local Government Area of Bayelsa state.
The three Dutch nationals were in a trip to the Niger Delta when they were abducted alongside Comrade Sunny Ofehe, Chief Executive Director of Hope for Niger Delta Campaign (HNDC), and Femi Soewu, a Creative Director of Africaweb Television.
The trios were in the Niger Delta to inspect a hospital built in Amatu II through a Chevron GMoU programme and see how they could help the locals sustain the hospital through medical support and international partnership.
The two Nigerians who were among the victims were blindfolded and eventually released on Monday night and left in a location in Bomadi local government area of Delta state but the kidnappers had held on to the trio of Erhard, Marrianne and Jan dries.
It was not clear if any ransom was paid by the kidnappers had first demanded for N350million for their release.
Sources said that the ransom was later reduced to N98million, then to N15million for each of the victims, thus making the sum to be N45million.
The last amount demanded as ransom by the militants before they were released on Saturday was N10million which amount to 45,000 euro.
A reliable source said that either the police or the Bayelsa state government were involved or aware of the release of the hostages until last Saturday night when the hostages were brought before the state deputy governor, Rear Admiral John Jonah.
The state deputy governor on Saturday night handed over the three Dutch to the Netherlands Ambassador to Nigerian after they were brought to the Government House, Onopa, Yenagoa by the state police commissioner, Hilary Opara.
