According to reports the four suspects were apprehended by villagers at different points over the last six days, before handing them over to the police.
The community chairman of Enekorogha town, Michael Ogobiri, told the BBC that villagers were searching the dense creeks and jungle to try to find the victims.
Police say the main suspects are a militant group called the Karowei. Police believe this latest incident is a response to a surge in military operations against the militants.
