Four people have been arrested in connection with the kidnapping of four British people in southern Nigeria, according to a BBC report.
The four Britons who were taken last Friday were Christian missionaries providing free medical services in the rural town of Enekorogha.
According to local leaders the four suspects were apprehended by villagers at different points over the last six days, before being given up 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.
There are many small armed groups in the oil-rich Niger Delta area who oppose government control over oil resources – and kidnappings by these groups are common.
Police believe this latest incident is a response to a surge in military operations against the militants.
