- A local leader Chief Theo Fakama said locals were 'saddened' by the kidnapping
Four Britons have been kidnapped in Nigeria's southern Delta state, a police official said on Wednesday.
Police are attempting to rescue the group, who are thought to have been taken on October 13 by a militant group renowned for demanding ransoms.
The four had been providing 'free medical care and religious activities' in the Burutu area of Delta state, said Chief Theo Fakama, from the local Enukorowa community.
David Donovan, a former GP from Cambridge, and his wife Shirley, both 57, were identified by The Times as two of the four people taken from their accommodation last Friday.
Together they run a charity called New Foundations, providing medical care to remote villages.
Their two sons Julian and Aiden are understood to also work for the charity, though it is not believed they got caught up in the kidnap.
The two other victims were named as Alana and Tyan, according to The Times.
Police chief Fakama said locals were 'saddened' by the kidnapping as the victims had 'brought succour to residents of the community for the past three years'.
Kidnapping for ransom is a common problem in parts of Nigeria.
A number of foreigners have, in the last few years, been kidnapped in the Niger Delta region, which holds most of the country's crude oil - the country's economic mainstay.
'The abductors have not made any contact but we are doing our investigations to know the motive and have them rescued without jeopardising their lives,' said Aniamaka.
