A Scottish oil worker has been abducted in southern Nigeria.
A security contractor said the man was working for an oil services firm when he was seized by unidentified gunmen in the city of Port Harcourt.
No-one has claimed responsibility for the kidnapping which happened late on Thursday.
More than 200 foreign workers have been abducted during almost three years of growing violence in the oil-rich Niger Delta region.
Most of them have been released unharmed, often after a ransom was paid.
The Movement for the Emancipation of the Niger Delta (Mend), the main militant group in the region, is still holding two Britons it said it had “rescued” in early October after pirates seized them from an oil supply vessel on 9 Sept.
Mend has said it is holding the two men as leverage for the release of its suspected leader, Henry Okah, who is on trial in the central city of Jos on treason and gun-running charges.
Lt Col Musa Sagir, a local military spokesman, said the man was seized in an upmarket part of town.
A spokesman for the British High Commission said: “I can confirm there was an incident in Port Harcourt on Thursday 27th where a British national was abducted.”
Unrest in the Niger Delta has reduced Nigeria’s oil output by about a quarter since 2006.
